    摘要： A measuring instrument for contactless detection of an angle of rotation comprises a carrier plate (52) consisting of a magnetically soft material that serves as a rotor. The stator of the sensor comprises at least two parts, the ends (18 and 17) of which terminate in two planes. The measuring gap (M1) containing an element (20) that is sensitive to a magnetic field is located between the ends (18, 17). Due to the fact that the ends (17, 18) of the two stator parts (13, 14) terminate in different planes, the measuring element (20) can be situated in a very small measuring gap (M1) in which the magnetic flux of the magnet (5) can be concentrated.

    摘要： A measuring instrument for contactless detection of an angle of rotation &ggr; is comprised of a supporting plate (14) made of soft magnetic material, which serves as a rotor. Two segments (16, 17) that are separated by a slot (21) and a spacing gap (22) are disposed in a plane in relation to the supporting plate (14). The supporting plate (14) is attached to the axle (11), whose projection (12) or the axle (11) itself is comprised of magnetically conductive material. The supporting plate (14) has a magnet (15) disposed on it, which is embodied as smaller than the angle of rotation &ggr; to be measured. The magnet (15) can be embodied of one or several parts. Through the disposition of the magnet (15), 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.

    摘要： A measuring instrument for contactless detection of an angle of rotation is comprised of a supporting plate (14) made of soft magnetic material, which serves as a rotor. Two segments (16, 17, 16a) that are separated by a slot (21), a spacing gap (22), and a third gap (60) are disposed in a plane in relation to the supporting plate (14). The spacing gap (22) in this case is embodied in the segment (17) in the form of a recess. The gap (60), however, is disposed in the segment (16a), likewise in the form of a recess. The ratio of the size of the spacing gap (22) to the gap (60) can be modulated so that an offset shift of the characteristic curve is produced.

    摘要： A measuring device for contactless detection of a rotational angle (&agr;) comprises a carrier plate (12), made of soft-magnetic material, which acts as a rotor. Two segments (15, 16) separated by a slit (17) are disposed in a plane parallel to the carrier plate (12). Disposed on one of the segments (16) is a short-circuit piece (20), and all these parts are of soft-magnetic material. The short-circuit piece (20) and the segments (15, 16) serve to guide the magnetic flux that is generated by a permanent magnet (13) disposed on the carrier plate (12). Since the short-circuit piece (20) protrudes past the carrier plate (12), or in a further feature the carrier plate (12) protrudes past the short-circuit piece (20), insensitivity to axial or radial play is possible. Furthermore, the measuring device is relatively simple and space-saving in design.
