Abstract
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.
