FC22 Compression Load Cell (0-25 lbs) - FC2231-0000-0025L

ID: 3121_0
This load cell measures compressive forces of up to 25 lbs and connects directly to a Voltage Input.

Discontinued

Replaced by the 3136_0 - Button Load Cell (0-50kg) - CZL204E using the 1046_0 - PhidgetBridge 4-Input

The FC22 is a medium compression force sensor that offers excellent performance at a reasonable cost. The 3121 offers normalized zero and span for interchangeability and is thermally compensated for changes in zero and span with respect to temperature.


The 3121 can be used in applications such as Robotics End-Effectors, Variable Force Control, Load and Compression Sensing, Contact Sensing, and Weighing.


The 3121 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.


Comes packaged with

  • Attached 60cm cable (2")
