Resistive load cells for seat belts (measuring range 16 kN) / M51111

Resistive load cells for seat belts (measuring range 16 kN)


The resistive load cells of family Type M51111 are designed to measure forces on the safety belt during a crash test, with a negligible impact on the belt’s performance.
  • Lightweight sensor
  • Low interpolation deviation
  • Sensitivity (typical): 130 μV/V/kN
  • Measuring range: 16 kN
  • ID module inside load cell optionally available
  • Calibration conforming to ISO / TS 17242 (third degree polynominal)
This sensor is comprised of a main body and two removeable bars. The main body is equipped with strain gauges. Due to its superior design the safety belt force transmission into the main body is ideal. The acting force mechanically extends the main body. The built-in strain gauges, implemented as a Wheatstone type full bridge, change their resistance proportionally to the acting force. The sensor supports three essential targets for webbing load cells: an ultra-low weight thanks to its Titanium design, good technical specifications and an easy handling including a replaceable cable system. Due to its low weight it supports the demand to simultaneously apply more than one load cell at the webbing. The replaceable cable solution allows the user to quickly exchange a defect, sheared-off cable in just a few minutes. The cable is plugged-in with a miniature connector inside the housing and is protected against external loads. The seat belt load cell is deliverable with two different cable outlet designs: family Type M51111A (right-angled) or family Type M51111B (straight). Customized cable lengths, ID modules and connectors with specific pin assignments are optionally available for both variants.
