FlexiForce A201 Sensor 25lbs
This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor.
The sensor has a force range of 0 - 25 lb. The force ranges stated are approximations. The dynamic range of this small, versatile force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor.
FlexiForce sensors are compared to other force sensors more linear, have less drift, have better rehabilitation, have wider range, and are less sensing area dependent.
- Force Sensor Length: 190.5 mm
- Sensing Size (Diameter/Width): 9.7 mm
- Standard Force: 111 N (11kg)
- Temperature Range: -40 °C to 60 °C
