Benefits of Using Strain Gauge Load Cells in Civil Engineering Projects

Strain gauge load cells provide data on force distribution, load shifts and structural performance. For major civil engineering projects in Western Australia, they’re an essential element of an accurate and compliant monitoring system.

Monitel tailors load cell monitoring systems to each and every project, enabling site managers and engineers to make informed, confident decisions.

This article explores 5 core benefits of strain gauge load cell monitoring and how a tailored system from Monitel ensures they deliver maximum value to your project. For more information, get in touch with one of our consultants.

1. Precise Force Measurement

Large structures are subject to changing load conditions. Strain gauge load cells offer the chance to monitor those variations at frequent intervals and with great accuracy. By monitoring props, anchors and struts, engineers can assess whether loads remain within design parameters and make an informed, evidence supported response should shifts occur.

2. Simple, Low Disruption Installation

Strain gauge load cells are a compact sensor and can be integrated into most structures without delaying works. Our installation experience includes within concrete pours, bolted onto steel members and incorporated into jacking systems.

Our consultants work closely with site managers to time installations to suit staging requirements.

3. Remote Monitoring Capabilities

Monitel sensors are compatible with most typically data loggers and telemetry systems to provide real time access to force measurements. They are also capable of remote monitoring, meaning you can access strain gauge load cell data whether you are based off or on site. This is particularly valuable in high risk or space constrained projects.

Our data dashboards also have alert functions, reducing the need for manual checks and ensuring site managers stay up to date and informed.

4. Long Term Durability and Stability

Long term monitoring is only successful when your sensors remain accurate and reliable over the whole monitoring period. Strain gauge load cells are renowned for their long term stability and built in protections against moisture and corrosion.

Monitel consultants have a deep understanding of Western Australian conditions and will select a sensor with proven success on sites like yours. All cabling and protective enclosures are also selected to suit project conditions.

5. Custom System Design for Complex Structures

Large civil projects are rarely simple. Engineers often have to work around curved tunnel segments, dynamic soil conditions and other factors. Strain gauge load cells can be customised in their form and data output to suit your monitoring needs.

Rather than relying on an off the shelf system, Monitel customises signal amplification, multiplexers and sensor selection to match your projects load type and regulatory requirements.

Interpreting Strain Gauge Load Cell Data

Strain gauge load cells are the perfect tool for applications where accurate, real time data is essential. But capturing that data is only one part of the job.

Monitel is proud to provide ongoing monitoring and maintenance assistance for strain gauge load cell systems we design. Our team will help you establish baselines, understand trends and troubleshoot possible failures.

This article explains how strain gauge load cell data works, how Monitel consultants can help you interpret it and how we ensure your readings stay accurate over time. For more information, contact our team.

How Strain Gauge Data Is Captured

This model of load cell has a strain gauge at its core. As the monitored structure deforms under the applied load, the gauge stretches or compresses to change its electrical resistance. That change is measured and then converted into a voltage signal, which can then be logged as a force value.

To ensure data accuracy, our consultants will choose the sensor best suited to your site and factor in conditions such as temperature as required.

Raw vs Processed Data

Raw data from a strain gauge may initially appear as:

  • Voltage (mV/V)

  • Strain (με or microstrain)

  • Resistance (Ω)

This raw data is typically converted by Monitel’s systems into meaningful engineering units (e.g., kN or t) using calibration constants and baseline readings. This conversion allows engineers to monitor absolute loads or changes over time without needing to interpret electrical signals.

Step 1: Establish Baselines and Thresholds

Before you form any meaningful insights based on strain gauge load cell data, it’s important to establish a baseline reading. Monitel does this immediately after installation under no or known load. Engineers and managers will reference this reading when interpreting future data.

From there, you can establish threshold values (and configure alert notifications) for operating ranges and critical limits.

Step 2: Understand Patterns and What They Indicate

Once your system is installed and calibrated, you’ll gain access to a trove of force data. Understanding patterns and changes in that data is critical to making informed decisions.

Here are some common situations on WA sites:

  • A gradual increase in load could indicate ground movement, material buildup or increased structural demand

  • Equipment failures, blasting and unexpected impacts could be the cause of a sudden load spike

  • A decreasing load may suggest loosening connections or the formation of a subsurface void

  • If your sensor is detecting no change when one is expected, it could be due to failed equipment, poor installation or signal loss

Proper application of strain gauge load cell data isn’t just about the number. Understanding how your data fits into site trends is key.

Step 3: Troubleshooting Common Issues

If your data appears flat or erratic, here are some common causes:

Symptom Possible Cause
Flatline data Sensor failure, broken wire or logger issue
Noisy signal Electrical interference, poor bonding or moisture intrusion
Unexpected values Calibration error, shifting baseline or structural damage
Drift over time Temperature changes, long-term strain creep or gauge fatigue

As strain gauge load cells are different to other sensors, it’s important to contact an experienced consultant for troubleshooting and repairs. Monitel offers ongoing maintenance support with our monitoring systems, on and off site.

Hydraulic vs Strain Gauge Load Cells: Which Is Best for Your Site?

Selecting the right type of load cell boils down to 4 key factors:

  • The site’s environment

  • Performance requirements for the project

  • Your data handling preferences

  • The length of the monitoring period

Both strain gauge and hydraulic load cells offer reliable and accurate measurements, but they fit differently into the above criteria. This comparison unpacks the differences in these two technologies to assist you in making an informed monitoring decision.

For more information or to enquire about sensor installation, contact Monitel today.

What Are Strain Gauge Load Cells?

Strain gauge load cells measure force with electrical resistance. As a load is applied to the cell, an internal steel or aluminium element will deform, changing the resistance in the attached strain gauge(s). Wheatstone bridge circuits convert these changes into electrical signals that are representative of the applied load.

Strain gauge load cells are a sensor known for their high sensitivity, compact design and compatibility with most typical data logging systems.

What Are Hydraulic Load Cells?

Hydraulic load cells have a different working mechanism, using fluid pressure to measure the force of an applied load. An internal diaphragm compresses, moving fluid into a pressure transducer. The resulting pressure change corresponds to the force applied the load. Because there are no electrical components at the sensing point, hydraulic load cells are ideal for:

  • Remote environments

  • Sites in harsh or dangerous climates

  • Long term deployments on powerless sites

  • Areas with significant EMI

How They’re Different

Installation

Strain Gauge:

  • Requires wiring, connectors and robust shielding

  • Must be carefully installed to avoid moisture damage

  • The precision required can make installation a lengthy process

Hydraulic:

  • No electrical components at the sensing point

  • Simple installation, often quicker on site

  • Tubing to the transducer must be protected

Our thoughts: Whilst strain gauge systems might offer greater flexibility and precision, hydraulic solutions are faster and cheaper to install on remote or inaccessible sites.

Measurement Precision

Strain Gauge:

  • Extremely sensitive with high resolution

  • Well suited to dynamic measurements and short term tests

  • When properly installed, can be accurate down to millivolt range

Hydraulic:

  • Incredibly stable under static conditions

  • Can experience minor hysteresis depending on fluid type

  • Precision can vary in dynamic conditions

Our thoughts: For a fast, high resolution response, a strain gauge load cell is the best choice.

Electrical Interference and Harsh Environments

Strain Gauge:

  • Can be vulnerable to EMI, especially near manufacturing areas

  • Requires shielding and careful grounding to negate excessive interference

Hydraulic:

  • Immune to EMI as it utilises a mechanical sensing mechanism

  • Ideal for high voltage zones or electrically noisy environments

Our thoughts: If your site is in a harsh or electrically active area, a hydraulic load cell is the safest choice.

Long-Term Stability and Maintenance

Strain Gauge:

  • Typically stable but can be affected by corrosion, cable damage and signal drift as the monitoring period progresses

  • Requires regular inspection of connectors and seals to ensure accuracy

Hydraulic:

  • Very stable in static load measurement

  • Fewer electronic parts reduce the risk of long term failure

  • Must be regularly monitored for fluid leaks or temperature effects, which can impact accuracy

Our thoughts: If you are designing a long term monitoring system, a hydraulic sensor’s accuracy and minimal maintenance requirements make it a suitable choice.

A Quick Guide for Common WA Scenarios

Our consultants have a deep knowledge of Western Australia’s regulatory and environmental conditions and use that understanding to create effective, efficient monitoring solutions.

Tailoring Systems Based on Site Requirements

When selecting a load cell type, we consider:

  • Data Frequency – Strain gauges are best when forces are changing rapidly

  • Environment – If the site is remote or EMI prone, a hydraulic cell is best

  • Power Access – No power? Hydraulic is your only option

  • Longevity vs Agility – Strain gauges might be more agile, but they’ll need more maintenance over time

Monitel will assess site conditions to determine which technology is most suitable and advise you of an appropriate monitoring plan.

Product Agnostic Approach

At Monitel, we pride ourselves on taking a product and brand agnostic approach. We are not tied to any one supplier and instead work with a range of load cell models and attachments to create the most compatible and lasting solution for each site.

Our focus is on accurate data and practical installation, not margins and markups. You’ll never be sold equipment you don’t need and will always be able to upgrade or scale in time.

How a Strain Gauge Based Load Cell Measures Force

Strain gauge load cells are critical for accurate force and load measurement in both geotechnical and structural applications. They deliver precise and repeatable data across multiple sectors and applications:

  • Mining

  • Infrastructure

  • Bridge structures

  • Verifying bearing loads

  • Other uses

In this article, we explain how strain gauge load cells work, how they provide such accurate data and how Monitel consultants use their local knowledge to ensure maximum sensor performance across Western Australia. For more information or to discuss your site, get in touch.

What Is a Strain Gauge Load Cell?

A strain gauge load cell is a sensor that converts mechanical force into an electrical signal using a strain sensitive material that deforms under an applied load. Attached to that material is one or more gauges that change resistance as they are stretched or compressed. That change is representative of deformation, which is proportional to the applied load.

The electrical signal is measurable, can be logged in most standard data systems and is used to interpret how much force is being applied to a structure.

The Wheatstone Bridge

A Wheatstone bridge circuit is what converts resistance changes into a readable output. It improves sensor sensitivity and can detect millivolt range signal variations. Monitel typically employs one of two setups:

  • Full bridge configurations using four strain gauges, increasing output sensitivity and improving temperature compensation.

  • Half or quarter bridge arrangements in simpler or constrained installations

Our consultants select a bridge configuration that aligns with the measurement range, environmental constraints and your monitoring goals.

Factors That Influence Data Accuracy

The accuracy of a strain gauge load cell’s performance is dictated by a host of internal and external factors. These include:

Material and Geometry of the Sensing Element

The mechanical body of the cell is designed to deform within a predictable and, importantly, uniform way. Most units are made from either steel or aluminium and selecting the right material is critical in resisting corrosion, fatigue and creep over time. Monitel consultants can assist you with sensor selection.

Strain Gauge Placement

Gauges are placed at points of maximum strain on the cell body. Poor attachment will limit the accuracy of your monitoring, whether it be through misalignment or uneven bonding. Our team works closely with suppliers to ensure gauge placement is tailored to each installation.

Calibration

A load cell must be calibrated against known forces to record linear data. Monitel ensures the calibration process accounts for manufacturing variances and geotechnical realities.

Temperature Compensation

Strain gauges are prone to thermal expansion, which, left unaddressed, can alter readings. Most units have an inbuilt temperature compensation gauge but, if not, our consultants will pair a suitable tool that factors changes into your data interpretation.

Signal Amplification and Shielding

Signal condition is essential to accurate load cell data. Monitel installs amplifiers close to the unit to minimise noise over long cable runs and properly shields wiring from electrical interference.

How Monitel Maximises Accuracy in the Field

Our consultants have vast experience completing precision monitoring on some of Western Australia’s harshest, most remote sites. To ensure accuracy in extreme temperatures and dynamic environments, we use:

  • Rugged Housing: Sensors are corrosion resistant, have ingress protection and are maximised for long term stability

  • Pre-Installation Testing: All units are tested prior to deployment to confirm calibration and signal integrity

  • Integrated Data Acquisition: Sensors are connected to your telemetry and logging systems for remote access and automated recording

The Monitel approach is designed to ensure that data is accurate, consistent and easily interpreted by site managers.

Hydraulic Load Cell Calibration: What Every Site Manager Needs to Know

Hydraulic load cells are a popular choice for monitoring programs on harsh or hard to access sites.

But like any other instrument, they need correct and scheduled calibration to provide meaningful data. Monitel’s consultants are experienced in calibrating hydraulic load cells and delivering the reports required by WA’s regulatory bodies.

This article explains what calibration is, why it matters and how our process ensures each hydraulic load cell performs reliably throughout its entire deployment. For more information or to discuss your site, contact Monitel.

What Is Calibration and Why Does It Matter?

Calibration is the process of verifying that a load cell is producing accurate force measurements within its working range. For a hydraulic load cell, this means ensuring internal fluid pressure corresponds precisely with the applied load.

Calibration is essential for any type of sensor, because with out it:

  • Site managers may receive incorrect readings that either underestimate or overestimate force

  • Data may not be an accurate reflection of field conditions

But most importantly, sensor data informs critical decisions. Should units be poorly calibrated, even a 5-10% deviation can cause misinterpretations that lead to structural failures, safety risks and regulatory violations.

How Monitel Consultants Perform Hydraulic Load Cell Calibration

At Monitel, our consultants calibrate hydraulic load cells in controlled environments, using widely accepted methods and traceable standards.

Our process looks like this:

  1. Bench Setup: The load cell is installed in a test rig, where a known load is incrementally applied

  2. Fluid Pressurisation: As each increment is applied, our consultants record rises in fluid pressure

  3. Verification Against Standards: We compare the recorded levels against known force values to assess repeatability and accuracy

  4. Curve Creation: We create a calibration curve that maps pressure to actual force, assisting them in assessing the sensor’s performance

  5. Certificate Issued: Site managers are provided a full calibration report, detailing traceable references, performance metrics and recommendations for further action

What to Consider When Recalibrating in the Field

When recalibrating a hydraulic load cell that has already been deployed, Monitel consultants account for:

  • Zeroing after installation, especially if the sensor is connected via long tubing runs or if fluid levels shift

  • Any damage to surface indicators or abnormal readings, which could require gauge replacements

  • Fluid chamber integrity checks, ensuring readings aren’t affected by air ingress or evaporation

Our team can also assist with calibrating vibrating wire and strain gauge load cells during staged loading or excavation phases.

FAQs

Because they work on a simple principle and have a robust construction, hydraulic load cells maintain a remarkable stability over time.

Nontheless, our consultants would recommend:

  • Initial calibration before each deployment

  • Mid project verification for long term installations or if the sensor is exposed to an extreme, volatile climate

  • Post retrieval recalibration if you plan to use that same unit in the future

This shcedule will ensure continued data quality and support regulatory compliance.

A well calibrated load cell means easily traceable data. That’s a core compliance requirement for industires like mining and infrastructure.

Monitel supports your compliance by integrating calibration data with force data. Our dashboards allow site managers to trace measurements, and the relevant calibrations, from the load event onwards.

It does.

Longer tubing has a direct impact on internal pressures and the way the system responds. Monitel consultants account for this during calibration and will advise you of interpretation techniques that maintain accuracy.

5 Ways a Hydraulic Load Cell Can Support Dam Management

On remote Western Australian sites, dams and storage facilities require constant monitoring to protect people and the environment.

Hydraulic load cells are an ideal choice for this task, with their rugged and robust construction offering protection against the harsh and corrosive nature of dam activity. Monitel is proud to have deployed this sensor on sites across WA to gather accurate and reliable structural stress data.

This post explains 6 ways hydraulic load cell monitoring can support dam infrastructure and how Monitel can install a system on your site. For more information, contact our team.

What Is a Hydraulic Load Cell?

A hydraulic load cell is a hardy sensor with a simple working principle: using fluid pressure transmission to measure applied loads.

When force is applied to the load bearing surface, it compresses the sensor’s internal chamber and the enclosed fluid. This pressure change can be read at the surface through either a manual gauge or pressure transducer.

Hydraulic systems have a simple construction, with no electrical components at the measuring points. This makes them strong, durable and suited to harsh or corrosive conditions like those found in dams.

6 Ways Hydraulic Load Cells Fit into Dam Management

1. Monitoring Anchor Loads in Dams

Many dams use ground anchors to stabilise embankments and retaining structures. Hydraulic load cells can be installed directly on to these anchors, measuring tension force.

This data verifies whether loads are within design limits and detects any progressive loading that could indicate shifting or instability within the dam wall.

2. Measuring Force in Retrofitted Systems

Older, riskier facilities may be reinforced with struts or props during maintenance or raising stages. Hydraulic load cells can monitor these supports, offering a non-intrusive, corrosion resistant option where other sensors would falter.

3. Long Term Structural Monitoring in Corrosive Conditions

Dam water is often riddled with chemically aggressive substances hostile to many types of instrumentation. But hydraulic load cells hold up in these conditions, boasting:

  • No electrical components at the measurement point

  • Ceramic diaphragms

  • Stainless steel housings

These allow for reliable performance over long periods.

4. Early Warning Systems for Settlement and Load Redistribution

Force monitoring doesn’t have to be reactive. By installing hydraulic load cells at key points in the embankment structure, site managers can detect any unexpected changes in force distribution before they escalate into major issues.

Think of it as an early warning system, triggering closer inspection or emergency protocols.

5. Monitoring Internal Embankment Forces

Hydraulic load cells can be installed within embankments to track internal stresses during staged construction. This helps site managers identify compaction inconsistencies as the dam rises.

6. Operational Safety and Design Validation

Because they can withstand aggressive conditions, hydraulic load cells provide long term data on how loads are evolving under operational conditions. This can be used to validate design assumptions and support regulatory compliance, ensuring the safety of the structure.

Our Monitoring Services

At Monitel, we strive to deliver hydraulic load cell solutions that integrate seamlessly into wider monitoring programs. Our services include:

  • System design and supply of load cells from trusted manufacturers

How to Read and Log Hydraulic Load Cell Data

Hydraulic load cells are a hardy instrument for monitoring force in remote and unforgiving environments. Their rugged build makes them a popular choice where other sensors will almost certainly fail.

But their accuracy and effectiveness hinges on more than just the sensor – how readings are captured, logged and interpreted is just as important to the quality of your data. Monitel systems are designed to maximise sensor performance and ensure data makes sense. Our consultants provide end to end support, assisting from sensor selection through to regulatory reporting.

In this article, we break down how hydraulic load cells output data and how you can ensure it’s accurate. For more information or to discuss your site’s requirements, contact Monitel.

Understanding Hydraulic Load Cell Outputs

Hydraulic load cells operate on a simple working principle: fluid pressure.

As pressure is applied to the cell body, a sealed fluid is compressed, which in turn exerts pressure on a measuring device. This pressure is proportional to the applied load.

Monitel’s load cell systems are compatible with two ways of reading data:

  • Bourdon Gauges: Data is read manually on this mechanical gauge, ideal for quick checks or sites with no power access

  • Pressure Transducer: Pressure is converted into an electrical signal, which is then sent to a data logger for automated monitoring

Each method offers its own benefits. The right fit for your site will be determined by your required accuracy, frequency of monitoring and how the sensor integrates with other instruments.

Using a Bourdon Gauge

A Bourdon gauge’s manual readings are often chosen for low risk projects or when resources are limited.

To ensure reliable data, Monitel installs gauges inside weatherproof enclosures and:

  • Records readings at consistent intervals (whether that be daily or weekly)

  • Logs external factors like temperature, weather and site conditions alongside readings

  • Uses calibrated gauges and routinely checks for mechanical drift

Used for short term projects or visual verification, Bourdon gauges work fine on their own. But should you need long term monitoring or threshold alerts, they will need to be paired with data loggers.

Using Pressure Transducers

Pressure transducers allow site managers to track real time data with minimal manual inputs. By converting pressure measurements into a standardised electrical signal, they enable:

  • Continuous data capture over extended periods

  • Integration with remote data loggers, telemetry systems or SCADA

  • Automated threshold notifications and reporting

Monitel consultants will typically install pressure transducers as part of an integrated system. Load cells, power supply and data loggers are combined in weatherproof enclosures to transmit measurements to your central database via cellular or satellite networks.

4 Tips for Accurate and Reliable Data Logging with Hydraulic Load Cells

  • Protect Tubing and Connections: Use reinforced lines and secure fittings to prevent any damage or leakage to your equipment.

  • Ventilation: Ensure the fluid system is properly vented to avoid trapped air, which can skew results.

  • Temperature Compensation: Where possible, choose sensors or loggers with built in temperature adjustment. This is especially important for climate volatile sites.

  • Routine Verification: Schedule periodic checks with Monitel consultants to validate logger accuracy against manual readings.

Hydraulic Load Cells for Harsh and Corrosive Environments

Across WA, mining operations, coastal infrastructure and chemical processing sites must stand up to unpredictable and corrosive climates. Many standard sensors simply cannot cope, affecting the reliability and accuracy of your monitoring data.

Hydraulic load cells are built differently, holding no electronic components at the measurement point to offer a robust alternative that can stand up to environmental extremes.

In this post, we explain why and how hydraulic load cells deliver consistent performance in unforgiving conditions and how Monitel incorporates them into monitoring solutions across Western Australia. To discuss your project’s requirements, get in touch with our team.

The Harsh Reality of Corrosive Environments

WA projects are no strangers to heat, salinity, dust and chemical exposure. Regardless of their purposes, any monitoring instruments must be resilient to these conditions over long periods of time.

Hydraulic load cells are renowned for exactly that. With a rugged construction and tightly sealed fluid chamber, they’re a go to choice in environments where electrical sensors will almost certainly degrade or fail. Hydraulic load cells excel in:

  • Corrosive settings like tailings dams and waste treatment areas

  • Remote installations with limited power supply

  • High vibration zones

  • Ocean adjacent structures where salt and humidity can cause issues

Why Do Hydraulic Load Cells Perform So Well in Extreme Conditions?

Hydraulic load cells have a simple working principle:

  1. A load is applied

  2. That load compresses an internal diaphragm

  3. Subsequently, pressure increases in the fluid filled chamber

  4. Data is measured by a remote readout

A hydraulic load cell’s key advantage is that, unlike strain gauge and vibrating wire sensors, its sensing component is separate from the measurement site. That means electronic components are protected from the environment and the unit can be deployed in less forgiving terrain.

Other advantages include the mechanical simplicity, stability in volatile temperatures and the quality of the sensor’s housing and sealing.

When to Choose Hydraulic Over Other Load Cells

By now, you might have an inkling that the hydraulic load cell thrives in scenarios where stain gauge and vibrating wire options often falter. Monitel consultants opt for a hydraulic unit when:

  • Power supply or infrastructure is limited

  • Equipment corrosion is a major concern

  • The project only requires a short to mid term monitoring solution

  • The site requires a simplistic installation

A hydraulic load cell might not offer the same precision and automation as other types, but their hardiness makes them a practical solution for harsh conditions.

How Monitel Supports WA Industry with Hydraulic Load Cells

At Monitel, our team understands that, in WA, every project is different. That’s why we design load cell monitoring systems that address site specific risks and account for corrosion dangers. Our deployment history includes:

  • Load monitoring on anchors and props

Understanding Strain Gauge, Hydraulic and Other Load Cell Outputs: How to Choose the Right Signal for Your Project

Load cells are a critical tool for many Western Australian projects, measuring the loads, stresses and forces that impact man made and natural structures.

Whilst strain gauge, hydraulic and other load cells may all measure the same thing, how they output that information can vary. Selecting the right signal format is essential in securing accurate and reliable data.

In this article, we break down the four main load cell outputs and how they could (or couldn’t) work on your site. For more information, contact Monitel.

1. Millivolt (mV/V) Output

This is the most common signal output for strain gauge load cells. It’s a low level, analogue option proportional to the excitation voltage applied (usually around 2 mV/V).

Pros

  • Incredibly sensitive and accurate

  • Works with most typical data acquisition systems

  • Perfect for short cable runs and laboratory work

Cons

  • The low voltage signal is prone to electrical interference

  • A stable excitation voltage is essential

  • Requires significant amplification for success over long cable lengths

How we use it

Monitel consultants opt for a millivolt signal when the logger/unit is located near to the load cell.

2. 4–20 mA Current Loop

In many industries, this is the standard. Instead of voltage, the load cell transmits a current proportional to the load applied. The current sits in the 4 to 20 mA range.

It’s a popular choice for remote field monitoring where sites may be hazardous or hard to access.

Pros

  • Great stability over long distances

  • Largely immune to voltage drops and electrical interference

  • Easy to integrate with remote monitoring systems

Cons

  • More costly than most other options

  • Signal represents an averaged, less specific force

How we use it

Most WA mining projects are in harsh, remote environments, so our consultants often use this current when monitoring tailings dams and bridge foundations.

3. Vibrating Wire (VW) Frequency

Many load cells use vibrating wire technology that converts force into a frequency. That frequency corresponds to a wire tension altered by the applied load.

  • Excellent long term stability

  • Highly resistant to harsh climates

  • Compatible with long cable runs and geotechnical deployments

Cons

  • Only compatible with specialised VW readouts or loggers

  • More expensive than a standard strain gauge model

How we use it

In geotechnical settings, long term accuracy is often more important than frequent samples. That’s why our consultants utilise this signal in embankments, tunnels and dams.

4. Digital Outputs (RS-485, Modbus and more)

Digital outputs convert an analogue signal and transmit it via protocols such as RS-485 and Modbus. They are most common in factory settings but are beginning to emerge as a popular choice in field monitoring.

Pros

  • Immune to analogue noise

  • Easily networked for multi point systems

  • Integrates seamlessly with modern loggers

  • Precise, complex configuration process

How we use it

Monitel deploys this signal in complex, multi parameter monitoring solutions where load data is networked with other instrumentation.

Geosense and Soil Instruments Output Options

Monitel is proud of our brand and product agnostic approach – we have no allegiance to any one sensor or company. Nonetheless, many of the load cells we use are supplied by Geosense or Soil Instruments. Their configurations include:

  • Geosense: Offers strain gauge load cells with mV/V, 4–20 mA, or VW outputs

  • Soil Instruments: Well respected for their VW systems with integrated readout options

How Monitel Helps You Find a Signal Output

Our team understands that a one-size-fits-all approach doesn’t work for WA operators.

Whether you’re in the South West or the Pilbara, we’ll assess site conditions, distance to logging equipment, monitoring objectives and regulatory demands to determine the best load cell type and output format. Other considerations include:

  • Environmental noise: Electrically noisy sites are best suited to current or frequency outputs.

  • Existing systems: We’ll ensure new technology is compatible with your existing dataloggers, telemetry or SCADA.

  • Sampling frequency: More dynamic sites may require voltage or digital outputs.

  • Project duration: If you’re monitoring long term, we’ll look to stable, low drift technologies like vibrating wire.

How Strain Gauge and Other Load Cells Support Regulatory Compliance

If you’re managing an operation in Western Australia, it’s likely governed by strict industry regulations. Monitel designs load cell solutions to provide reliable data on force, weight and structural behaviour in mining and infrastructure projects.

This article explains how strain gauge, hydraulic and other load cells provide regulator ready data that fortifies your compliance. For more information or to arrange a consultation, get in touch with our team.

Why Load Monitoring Matters for Compliance

All levels of government require certain structures and equipment to be monitored for their stability. Common activities/components with load monitoring requirements include:

  • Ground anchors on temporary retaining walls

  • Measuring load on supports during excavation

  • Verifying load distribution across bridge bearings

With precise, real time load data, site managers can identify risks before a structural failure or regulatory breach occurs. Data also acts as evidence of due diligence during audits and inspections, or in the event of a workplace incident.

Regulations That Govern WA Projects

WA’s heavy industries are regulated by complex safety, environmental and engineering standards. Strain gauge, hydraulic and other load cells can be used to satisfy many of them, including:

  • DMIRS who impose rules around the monitoring of tailings dams, underground structures and other infrastructure in mining operations

  • NGER Scheme which regulates how load monitoring can contribute to energy use and emissions

  • AS Standards such as AS 3778, 1170 and 4100, which often require load cell monitoring to verify compliance

  • Work Health and Safety Regulations which regulate employee and occupant safety in structures

Our consultants will tailor your monitoring system to suit the regulatory requirements of your site.

How Load Cells Prove Site Safety

Load cells are a perfect addition to your compliance toolkit. They produce transparent data that acts as a digital footprint of what’s happening onsite. Figures reflecting stress changes, load shifts and other conditions can be used to:

  • Demonstrate adherence to site specific constraints

  • Identify risks before catastrophic failure

  • Show long term structural performance

Reliable, frequent and long term data is particularly valuable for structures where safety margins are tight – such as tailings dams and tunnels.

Common Compliance Focused Uses for Load Cells

Monitel has deployed load cells on sites in many different industries across Western Australia. Our experience includes:

  • Mining and resources, using strain gauge load cells to monitor collapse risks and ensure safe working conditions

  • Utilising hydraulic and vibrating wire load cells to monitor anchor forces in temporary structures

  • Gathering load data in bridge construction projects to ensure even load transfer

  • Monitoring long term stability in slope structures

Supporting Your Project with Regulator Ready Data

Our consultants work closely with engineers and site managers to ensure monitoring systems aren’t just collecting data. We create systems that keep load information traceable, clear and regulator ready by:

  • Selecting a load cell that suits the structure, environment and regulatory frameworks governing your site

  • Ensuring installation meets best practices

  • Integrating data logging and remote alerts as required

  • Providing ongoing support, including calibration checks and reporting assistance

User Friendly Data Systems

All load cells are paired with intuitive data logging and dashboard programs that eliminate any guesswork. Decision makers will be able to interpret data quickly and accurately and export evidence based reports when needed. These features can be used to support inspections and internal reviews.

Custom Alerts

Systems can also be configured with custom alerts and notifications, triggered when critical limits are exceeded. Options include:

  • SMS

  • Email

  • Intra-logging system alerts

They are often set for overloads, structural stress and unusual force. This feature supports swift and informed responses to critical incidents and acts as proof of due diligence to regulators.
