Frequently Asked Questions

What is the recommended excitation voltage for the GML669 sensor?

The Pro-Range GML669 load cell is designed for a recommended excitation voltage of 10 VDC. Operating within this specified voltage ensures optimal sensor performance, accurate output signal (1.0–1.5 mV/V), and maintains the stated accuracy specifications. Always use a stable, regulated DC power supply to power the sensor.

How do I interface this mV/V output sensor with a microcontroller or PLC?

The GML669's 1.0–1.5 mV/V analog output requires signal conditioning before connecting to a digital system. You will need an instrumentation amplifier or a dedicated load cell amplifier module (HX711, INA125, etc.) to amplify the small differential signal to a higher voltage range (e.g., 0-5V or 0-10V) suitable for an ADC. The amplified signal can then be read by microcontrollers like Arduino, Raspberry Pi, or industrial PLC analog input modules.

What is the difference between rated load and maximum load?

The rated load (1 kN for this model) is the maximum force the sensor is designed to measure within its specified accuracy band (±0.5% F.S.). Exceeding this load may cause permanent damage or shift calibration. Sensors often have a safe overload rating (e.g., 150% of rated load) for transient protection, but you should consult the manufacturer's full datasheet for specific maximum overload and ultimate load limits to ensure safe operation.

Can this sensor be used for tension or pulling force measurements?

No, the GML669 is specifically designed as a compression-only load cell. Its internal strain gauge and mechanical structure are optimized to measure forces applied along its central axis that compress the sensor. Applying tensile (pulling) forces can damage the sensor and will not provide accurate readings. For tension measurements, you would need a designated tension load cell or a universal (tension/compression) model.
