DESCRIPTION
The FC23 is a high compression force sensor that creates new markets previously unrealizable due to
cost and performance constraints. The FC23 offers normalized zero and span for interchangeability and is
thermally compensated for changes in zero and span with respect to temperature.
The FC23 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 FC23 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 FC23 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 models FS20 and FC22 for lower force applications.
