Pro-Range GML668B Tension Compression Force Sensor 50N - ±0.1% F.S Output 2.0±10% mV/V

The GML668B provides a ratiometric analog output of 2.0 mV/V. This means you must apply a stable excitation voltage (5-15 VDC) across the sensor's input wires. The output signal, measured across the output wires, will be a small DC voltage proportional to the applied force. This signal requires amplification via a strain gauge amplifier or instrumentation amplifier before being read by a PLC, data logger, or microcontroller ADC.

Yes, the GML668B is specifically designed as a dual-purpose tension and compression load cell. Its stainless steel structure and internal strain gauge arrangement are calibrated to measure both types of force accurately up to its 50 Newton rated capacity. Ensure the force is applied axially along the designated mounting points for correct measurement.

The sensor typically has a 4-wire configuration: red and black for excitation voltage (5-15 VDC), and green and white for the signal output. A full Wheatstone bridge completion and signal conditioning are required externally. For reliable connections, use shielded cable and proper strain relief at the sensor body to prevent noise and cable damage.

With its IP66 ingress protection rating, the sensor is protected against dust ingress and powerful water jets, making it suitable for damp or dusty industrial environments. However, it is not submersible. For prolonged outdoor use, additional protective enclosures for the cable connections and electronics are recommended.
