Abstract (en)
[origin: DE19852915A1] The inventive measuring device for the contactless measurement of an angle of rotation gamma consists of a soft-magnetic base plate (14) which serves as a rotor. Two segments (16, 17) are arranged in one plane with the base plate (14) and are separated by a slot (21) and a spacer gap (22). The base plate (14) is mounted on the pin (11). The extension (12) of said pin or the pin (11) itself consists of magnetically conductive material. A magnet (15) is arranged on the base plate (14). Said magnet (15) is smaller than the angle of rotation gamma and can be a single-block magnet or a magnet consisting of several members. The arrangement of the magnet (15) facilitates reproduction of various sections, for example, plateaus or sections deviating from the linear measuring line, within the measuring curve detected by the measuring device.
