The A301 is optimized for high volume manufacturing and ideal for embedding into products and applications.
The dynamic range of this small force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor.

How to Adjust the Force Range:
In order to measure higher forces, apply a lower drive voltage (-0.5 V, -0.25 V, etc.) and reduce the resistance of the feedback resistor (1kΩ min.) To measure lower forces, apply a higher drive voltage and increase the resistance of the feedback resistor. For an alternative to the recommended circuit, see the Related Electronics tab.
Linearity (Error): < ±3% of Full Scale (Line drawn from 0 to 50% load)
Repeatability: < ±2.5% (Conditioned Sensor, 80% of Full Force Applied)
Hysteresis: < 4.5 % of Full Scale (Conditioned Sensor, 80% of Full Force Applied)
Drift: <5% / logarithmic time (Constant Load of 25 lb (111 N))
Response Time: < 5 µsec (Time required for the sensor to respond to an input force; Impact load – recorded on Oscilloscope)
Operating Temperature: -40°C – 60°C (-40°F – 140°F)*
* Force reading change per degree of temperature change = 0.36%/ºC (±0.2%/ºF)
