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.
