Beschreibung
Zusammenfassung:	The present invention relates to a torque transducer with a shaft subject to torque about a longitudinal axis. It also relates to a transducer element integral with or carried by the shaft and remanently magnetised to emanate a component of magnetic field that is dependent on torque applied about said axis. A sensor coil is disposed about said element to generate a voltage/current in response to changes in said component. A load is connected to said sensor coil to enable a current circulate in the sensor and a receiver unit remote from said coil and responsive to a field emanated by said sensor coil to generate torque-dependent signal.
