Why do I need an excitation circuit to read force with FlexiForce A201 sensors?
You should use an excitation circuit such as the one shown here to provide a constant drive voltage/current and provide an output voltage that is proportional to the applied force. [Back to Top] Does the resistive element react similar to a semiconductor (diode, etc.) that varies conductance with applied voltage? Yes. [Back to Top] What is the resistance range of the sensor? The resistance range of the sensor is typically from >5M at no load to approximately 5k at full load. This can vary depending on the electronics being used to drive and read the sensor. [Back to Top] How do I connect the sensor after it has been trimmed? If Tekscan trims the A201 sensors to two inches, four inches, or six inches, the sensor will come with three (3) male square pin connectors spaced at 0.1″ (2.54mm). If you trim the sensor yourself, you will need to re-connect the sensor using one of two methods. You can purchase staked pin connectors and a crimping tool, or you can use a conductive epoxy to adhere
