Magnetostrictive car crash detection deformation sensor has magnetic field change to electrical signal transducer with diagnosis unit using centre contact on sensor induction coil

摘要

A magnetostrictive car crash detection deformation sensor (100) has a magnetic field change to electrical signal (103) transducer (102) with diagnosis unit (201) to test the sensor functionality using a centre contact on the induction coil detector (101). Independent claims are included for procedures using the deformation sensor.
