Elektromagnetischer Sensor

摘要

An electromagnetic sensor (1) serves to detect measurement values produced on the basis of a magnetic anisotropy in the measurement region. A core (2) carries an excitation winding (8), the central plane of which coincides with a plane of symmetry of the core (2). It divides the base (3) into two halves. A detector winding (12) crosses the excitation winding (8) in such a way that the magnetic flux leaves the detector windings (12) unaffected when there is magnetic isotropy in the measurement region, but when there is magnetic anisotropy it passes through to a part of the detector winding. A compact, accurately measuring sensor is obtained in this manner.
