Abstract
A measuring instrument for contactless detection of an angle of rotation &ggr; is comprised of a supporting plate ( ) made of soft magnetic material, which serves as a rotor. Two segments ( ) that are separated by a slot ( ) and a spacing gap ( ) are disposed in a plane in relation to the supporting plate ( ). The supporting plate ( ) is attached to the axle ( ), whose projection ( ) or the axle ( ) itself is comprised of magnetically conductive material. The supporting plate ( ) has a magnet ( ) disposed on it, which is embodied as smaller than the angle of rotation &ggr; to be measured. The magnet ( ) can be embodied of one or several parts. Through the disposition of the magnet ( ), it is possible to produce different sections in the measurement curve detected by the measurement instrument, e.g. plateaus or sections which deviate from the linear measurement line.
