Abstract
The invention relates to a measuring arrangement for detecting a rotational movement between a first machine part (2) and a second machine part (3). The claimed measuring arrangement comprises a transducer wheel (10) which is rotationally secured to the first machine part (2), an absolute transducer (11) which is rotationally secured to the first machine part (2), an incremental sensor (27) which is rotationally secured to the second machine part (3) and an absolute sensor (28) which is rotationally secured to the second machine part (3). Said transducer wheel (10) comprises, in the direction of the periphery, an alternating sequence of cut-outs (16) and segments (17). Said absolute transducer (11) is secured to the transducer wheel (10) and marks a peripheral position of the transducer wheel (10). Said incremental sensor (27) scans the transducer wheel (10) and generates an incremental signal. The absolute sensor (28) scans the absolute transducer (11) and generates an absolute signal.
