Pro-Range GML668B Tension Compression Force Sensor 300N - ±0.1% F.S Output 2.0±10% mV/V

The GML668B load cell operates with a standard excitation voltage range of 5 to 15 Volts DC. A stable, regulated power supply within this range is recommended to ensure the accuracy and stability of the 2.0 mV/V output signal. Typical instrumentation amplifiers and signal conditioners provide 10V excitation.

Yes, the Pro-Range GML668B is specifically engineered as a tension and compression load cell. Its stainless steel construction and strain gauge design allow it to accurately measure forces up to 300N in both axial directions, making it suitable for applications like robotic gripping, press-fitting, and material testing.

The IP66 rating indicates the sensor is dust-tight (first digit '6') and protected against powerful water jets (second digit '6'). This makes the GML668B suitable for use in industrial environments where exposure to dust, debris, or wash-down procedures is a concern, ensuring long-term reliability.

The low-level millivolt-per-volt output requires signal conditioning. You will need a load cell amplifier or instrumentation amplifier module to amplify the signal to a usable voltage range (e.g., 0-5V or 4-20mA) for an ADC. For direct digital reading, a dedicated 24-bit ADC like the HX711 is commonly used with Arduino and similar platforms.

The sensor has a compensated temperature range of -10°C to +60°C. Within this range, internal circuitry minimizes output drift caused by temperature changes, ensuring measurement accuracy. For operation between -20°C to +80°C, slight variations in the zero point and sensitivity may occur and should be accounted for in high-precision applications.
