ABSTRACT:
A measuring device for contactless determination of relative angular position including a stator (10) provided with slotlike stator air gaps (14, 15), a rotor (12) rotatable relative to the stator with a main gap between it and the stator and a Hall element (16) arranged in at least one of the stator air gaps. Two ring magnets (21, 22) having magnetic polarities opposite to each other are provided in the interior wall of the stator (10). To measure a rotational angle of greater than .+-.75.degree. with a linear response measurement curve, the first ring magnet (15) extends around the rotor (11) over an angular range of greater than 180.degree.. When the null point of the magnetic induction B is shifted to the beginning of the linear range of the mechanical measuring range, particularly small rotation angles can be measured with a comparatively reduced measurement error.
