Absolute angle determining device e.g. for rotation of axis of rotation e.g. for measuring absolute angle of rotation of steering wheel, has measuring instrument for measurement of angle of rotation in reduced measuring range

摘要

The device has a measuring instrument (10) for the measurement of an angle of rotation in a reduced measuring range and a second measuring instrument (12) for the determination of an absolute angle range. The first measuring instrument is for the rotation axle (14) of a coupled rotor (16) and a stationary carrier relative to the rotor. Either on the rotor or on the carrier, coded ranges (18) are distributed and located in circumferential direction. On the carrier and or on the rotor a sensor (20) is provided for the rotation (14) of the coding of the coded range.
