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:

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.
