Magnetic measuring system.

摘要

A periodic, magnetic measurement scale (3) is scanned in the measurement direction by a sensing device (4) with at least one magnetic field sensitive element (5) to produce position dependent output signals. Position values are formed from the output signals by an evaluation device. The magnetic field sensitive element or elements is or are arranged in a plane parallel to the measurement scale and biassed by an auxiliary magnetic field (Y). The auxiliary field can be a high frequency alternating magnetic field, e.g. of rectangular or triangular waveform.
