The FC22 is a medium compression force sensor that offers excellent performance at a reasonable cost. The 3120 offers normalized zero and span for interchangeability and is thermally compensated for changes in zero and span with respect to temperature.
The 3120 can be used in applications such as Robotics End-Effectors, Variable Force Control, Load and Compression Sensing, Contact Sensing, and Weighing.
The 3120 incorporates MEAS’ proprietary Microfused™ technology which employs micromachined silicon piezoresistive strain gages fused with high temperature glass to a high performance stainless steel substrate. Microfused™ technology eliminates age-sensitive organic epoxies used in traditional load cell designs providing excellent long term span and zero stability.
The FC22 measures direct force and is therefore not subject to lead-die fatigue failure common with competitive designs which use a pressure capsule embedded within a silicone gel-filled cavity. Operating at very low strains, Microfused™ technology provides an essentially unlimited cycle life expectancy, superior resolution, and high over-range capabilities.

The easiest way to connect the sensor is to use a 3002 - Phidget Cable 60cm or a 3004 - Phidget Cable 350cm ; cut the Phidget cable to the desired length and solder the load cell wires to the Phidget cable as follows:
|3123 - Load Cell||Phidget Cable|
Then, connect the load cell to any device with an Analog Input.
