DESCRIPTION
The FC22 is a medium compression force sensor that creates new markets previously unrealizable due to cost
and performance constraints. The FC22 offers normalized zero and span for interchangeability and is thermally
compensated for changes in zero and span with respect to temperature.
The FC22 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.
Cost-optimization of the FC22 brings your OEM product to life whether you need thousands or millions of load
cells annually. Although the standard model is ideal for a wide range of applications, our dedicated design team
at our Load Cell Engineering Center is ready to provide you with custom designs for your OEM applications.
Please refer to the FS20 for lower force applications or the FC23 for higher force applications.
