NEW FT24 Tension Load Cells LOW COST Tension Ranges: 2, 5, 10, 25, 50, 100 Lbf. High Level or Millivolt Outputs Interchangeable Compact Easy to Fixture Design DESCRIPTION The FT24 Series Low Cost Tension 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 micromachined silicon piezoresistive strain gages fused with high temperature glass to a high performance stainless steel substrate. MicrofusedTM process eliminates age-sensitive organic epoxies used in classical load cell designs providing excellent long term span and zero stability. FEATURES Low cost Small size Low noise Robust: high over range capability High reliability Low deflection Low off center errors Fast response time Essentially unlimited cycle life 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 safety-critical automotive brake sensors. MSI's model FT24 is appropriate for use in all types of OEM appliance applications where high reliability and durability are critical. The FT24 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. 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 FT24 is fully thermally compensated for changes in zero and span with respect to temperature and offers normalized zero and span for interchangeability. Consult MSI for uncompensated super low cost variants of the FT24 load cell.
