NEW FC21 & FC22 Compression Load Cells LOW COST Compression Ranges: 2, 5, 10, 25, 50 and 100 Lbf. High Level or Millivolt Outputs Interchangeable Compact Easy to Fixture Design DESCRIPTION The FC21 and FC22 Series Low Cost Compression Force Sensors create new markets previously unrealizable due to cost and performance constraints. This series raises the bar in price and performance. MSI Sensors' proprietary MicrofusedTM technology, derived from demanding aerospace applications, employs micro- FEATURES Low cost Small size Low noise Robust: high overrange capability High reliability Low deflection Essentially unlimited cycle Life expectancy Low off center errors Fast response time From 2 to 100 lb ranges APPLICATIONS Medical infusion pumps Robotics end-effectors Variable force control Load and compression sensing Exercise machines Pumps Contact sensing Weighing machined 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 very 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 up to 4V. MicrofusedTM sensors are used in a variety of applications including bathroom scales, paint sprayers and safetycritical automotive brake sensors. MSI's models FC21 and FC22 are appropriate for use in all types of OEM weighing and force measurement applications where high reliability and accuracy are critical. From appliance controls to biomechanical force feedback, the FC21 and FC22 are 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. 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. The FC21 and FC22 are fully thermally compensated for changes in zero and span with respect to temperature and offer normalized zero and span for interchangeability. Consult MSI for uncompensated super low cost variants of the FC21 and FC22 instruments.
