Pressure sensor pads are electronic devices that capture physical force contact to generate some sort of a response. There is a truly endless amount of applications for pressure sensor pads, ranging from an input mechanism in a human-machine interface (HMI), a method to capture intruders in a force-sensitive security system, and beyond.
Technical Description:
They have a force range of 0-222 N (0-50 lb), specified with Tekscan electronics. The model is linear through a much lower range of 0-22N (0-5 lb), and is capable of measuring loads up to 44,482 N (10,000 lb).*
The dynamic range of this square force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor
