Abstract
A measuring instrument ( ) for contactless ascertainment of a rotation angle is made up of a support plate ( ) that is comprised of magnetically nonconductive material and serves as a rotor. A permanent magnet ( ), which is embodied as planar, is disposed on the support plate ( ) and its polarization direction is aligned diametrically to the axle ( ). If the Hall element ( ) is asymmetrically disposed, i.e. if the Hall element ( ) describes an elliptical rotary motion in relation to the permanent magnet ( ), then a steeply decreasing region and a flat region are produced in the curve of the output signal. No magnetic flux conducting parts are required in the measuring instrument ( ). Furthermore, it is very small and relatively easy to incorporate into systems and devices.
