DYNAMOMETER, PARTICULARLY FOR DETERMINING THE SEATING WEIGHT IN A MOTOR VEHICLE

摘要

Force measurement instrument (10) has a mounting (11) in which a permanent magnet (32) and a magnetic field sensor (35). The magnet is surrounded by ferromagnetic material and the distance from the magnet to the material is changed by a force (F) acting on the housing element. The change is distance results in a change in the magnet field strength, which is detected by the sensor and converted to a corresponding signal.
