The FS20 is a low compression force sensor that
creates new markets previously unrealizable due to cost
and performance constraints. The FS20 offers normalized
zero and span for interchangeability and is thermally
compensated for changes in zero and span with respect to
temperature.
The FS20 incorporates TE’s 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 FS20
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 FS20 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 FC22 and FC23 for higher force
applications.
