FlexiForce™ ESS301 Sensor

The ESS301 sensor is made from Tekscan’s Enhanced Stability Series (ESS) pressure sensitive ink. This allows for better performance in a wider range of operating and storage conditions. ESS301 was developed with OEM customers in mind and designed to reached the majority of our OEM customer’s test expectations.

ESS301 is available in one force range: 4.4 N (0 – 1 lb). 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 (see “How to Adjust the Force Range” within the Electronics tab on the left).

Sensor output is a function of many variables, including interface materials. Therefore, Tekscan recommends the user calibrate each sensor for the application. The graph below is an illustration of how a sensor can be used to measure varying force ranges by changing the feedback resistor (the graph below should not be used as a calibration chart).
