A rotary transducer has a detector device with a measurement sensor, used to generate a measurement signal representative of angular position and/or velocity of an object. The detector device has a rotary bearing and a material measure that can be rotated relative to the measurement sensor and is arranged in the measurement field of the latter. A monitoring device, connected to the measurement sensor, which can provide a state signal representative of the state of wear of the rotary transducer, is integrated in the rotary transducer. In order to be able to timely warn of mechanical failure of the rotary transducer, the monitoring device is provided with a register that can permanently store as value representative of the state of wear of the rotary bearing and is formed from the information relating to the angular position and/or velocity contained in the measurement signal.

Rotary transducer with monitoring of the bearing wear and method therefor

The invention relates to a device for detecting movements and/or positions of an object with the aid of voltage pulses induced by the field of adjacent magnets () in a coil (). In order to generate a sufficiently strong signal also at small relative speeds between the magnets () and the coil (), the coil () encloses a spring () in which a quick fore-and-aft movement can be induced by the magnetic fields of the magnets (), the magnetic poles of the spring () being reversed during said fore-and-aft movement.
