Load Cells - Tension and Compression

The FS20 Series Low Cost Compression Force Sensor creates new markets previously unrealizable due to cost and performance constraints. MSI Sensors’ proprietary MicrofusedTM technology, derived from demanding aerospace applications, employs micromachined silicon piezoresistive strain gages fused with high temperature glass to a high performance stainless steel substrate. MicrofusedTM technology eliminates age-sensitive organic epoxies used in classical load cell designs providing excellent long term span and zero stability. Operating at exceedingly low strains, MicrofusedTM technology provides gage factors greater than 100, an essentially unlimited cycle life expectancy, superior resolution, exceedingly high over-range margins without the need for stops and a ratiometric span of 3V. MicrofusedTM sensors are used in a variety of applications including bathroom scales, paint sprayers and safetycritical automotive brake sensors. Unlike competitive designs which use a pressure capsule embedded within a silicone gelfilled cavity the FS20 measures direct force. The FS20 is therefore not subject to lead-die fatigue failure common with competitive designs. The FS20 is the OEM designer’s dream-come-true; cost-optimized to bring your OEM products to life whether you need thousands or millions of load cells annually. The standard model is ideal for a wide range of applications. The FS20 is fully thermally compensated for changes in zero and span with respect to temperature and offers normalized zero and span for interchangeability.
