Abstract
An arrangement for detecting the angle of rotation of a rotatable element, in which, with evaluation of magnetically variable properties of a sensor arrangement, a first magnetic field, generated or varied by a rotatable element, is detectable in an evaluation circuit and usable for ascertaining the angle of rotation, wherein the sensor arrangement, utilizing the magnetoresistive effect, furnishes signals that can be associated unambiguously with one direction of the magnetic field B over a first angular range, in particular an angular range of 360°, having means to for is selective application of a magnetic auxiliary field B the sensor arrangement, by means of which signals a modification of the signals that can be associated with the direction of the first magnetic field B , attainable for the sake of unambiguous association of an angle over a second angular range, in particular 360°.
