Standard Model A201
The FlexiForce A201 is our standard sensor and meets the requirements
of most customers. The A201 is a thin and flexible piezoresistive force
sensor that is available off-the-shelf in a variety of lengths for easy proof
of concept. These ultra-thin sensors are ideal for non-intrusive force and
pressure measurement in a variety of applications. The A201 can be used
with our test & measurement, prototyping, and embedding electronics,
including the FlexiForce Sensor Characterization Kit, FlexiForce
Prototyping Kit, FlexiForce Quickstart Board, and the ELF™ System*.
You can also use your own electronics, or multimeter.

†
as Tested with Circuit Shown
This sensor can measure up to 4,448 N (1,000 lb).
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.
Sensor output is a function of many variables, including interface materials.
Therefore, Tekscan recommends the user calibrate each sensor for the application.
