Overview
The FN4055 tension seat belt load cell sensor measures with excellent accuracy the forces exerted on the seat belt.

Only the actual compression upon the seat belt is measured, as the sensor is insensitive to contact from the crash test dummy.  The FN4055 tension seat belt load cell is designed for very low range, like tests for kid’s security. It is protected against overload by mechanical stops. A similar sensor, EL20-S458, covers requests with higher ranges up to 25kN. With many years of experience as a designer and manufacturer of sensors, we often work with customers to design or customize sensors for specific uses and testing environments. On request, instruction documents can be provided to ease the selection and use of our sensors and provide helpful tips.
