The Phidgets FlexiForce Adapter makes it easy to interface a Tekscan FlexiForce Force Sensor to your PC. Just use the cable included with the adapter. The Phidgets even gives you a round plastic disc for the sensing pad. The FlexiForce sensor is an ultra-thin and flexible printed circuit, which can be easily integrated into most applications. With its paper-thin construction, flexibility and force measurement ability, the FlexiForce force sensor can measure force between almost any two surfaces and is durable enough to stand up to most environments.

FlexiForce has better force sensing properties, linearity, hysteresis, drift, and temperature sensitivity than any other thin-film force sensors. The "active sensing area" is a 0.375" diameter circle at the end of the sensor. Before using your FlexiForce Sensor, it is recommended that you read the Flexiforce FAQs and User Manual paying special attention to Calibration and Conditioning.

Good product, supporting documentation lacking

I bought this board to provide an off-the-shelf way to read in the load from the A401 flexiforce Sensor... the big round one rated for 1-25lbs. Well the sensor is capable of doing other force ranges including 0-1lb which is what I needed. Unfortunately this board is not able to adjust the feedback resistance so it only works for the 0-25lb range with the A401 sensor. I asked Robotshop via their support email for a circuit diagram of the board and they pointed me incorrectly to a single op-amp circuit on the Tekscan/flexiforce website. The actual circuit on the board is a single supply instrumentation amplifier circuit using 2 op-amps and it's tuned quite well for 0-25lbs. I also liked the cables and simple breakout connections for this board. Very competitively priced compared to purchasing the board offered by Tekscan themselves.
