The invention relates to a rotary transducer (1) and to a method for monitoring wear on the latter. The rotary transducer has a detector device (11) having at least one measurement sensor (12). During operation, the measurement sensor can be used to generate a measurement signal (13) which is representative of the angular position and/or velocity of an object which can be connected to the rotary transducer. The detector device (11) has at least one rotary bearing (15) and at least one material measure (16) which can be rotated, by means of the rotary bearing, relative to the measurement sensor and is arranged in the measurement field (17) of the latter. A monitoring device (20) which is connected to the measurement sensor such that data are transmitted and can be used, during operation, to output a state signal (23), which is representative of the state of wear of the rotary transducer, on the basis of the measurement signal is also integrated in the rotary transducer (1). In order to be able to warm of mechanical failure of the rotary transducer in good time, the monitoring device (20) is provided, according to the invention, with a register (25) which can permanently store a value which is representative of the state of wear of the rotary bearing and is formed form the information relating to the angular position and/or velocity which is contained in the measurement signal.
