Force Sensors & FSR Technology

An FSR works by utilizing a conductive polymer film that changes resistance when compressed by an applied force. When pressure is applied, more conductive particles come into contact, lowering resistance proportionally to the force. The output is read as an analog voltage or current signal. For industrial-grade accuracy, strain-gage based force sensors like those from SensorData Technologies offer superior linearity and repeatability.

A piezoelectric sensor generates a voltage signal in response to dynamic force changes and is best suited for measuring rapidly changing or impact forces. An FSR (Force Sensing Resistor) changes its electrical resistance under static or quasi-static loads and is suitable for simple presence detection. Strain-gage based force sensors, like SensorData's offerings, provide the highest accuracy for both static and dynamic force measurement.

SensorData Technologies offers force sensors across a wide capacity range. The F312 series covers 200 to 3,000 lbs, the F341-F347 series handles 5K to 500K lbs, the F502 ranges from 5K to 100K lbs, and the F654 covers 5K to 25K lbs. Multi-axis sensors also support various torque and thrust combinations. Custom capacities are available upon request.

SensorData force sensors are compatible with both AC carrier and DC strain gage signal conditioning electronics. This dual compatibility gives engineers flexibility in selecting instrumentation for their test systems. The company also offers in-house calibration services using customer-supplied electronics, ensuring your sensor performs accurately within your specific measurement chain.
