摘要： A measuring arrangement for distance or angle measurement and a corresponding measuring method are described. In accordance with one example, the measuring arrangement comprises a scale having magnetization which varies along a measuring direction and which brings about a correspondingly varying magnetic field. The measuring device furthermore comprises at least one scanning head which is permeated by the varying magnetic field depending on the relative position with respect to the scale in the measuring direction. The scanning head comprises the following: at least one ferromagnetic film having, on account of the magneto impedance effect, a local electrical impedance that is dependent on the magnetic field and varies along the measuring direction, and at least one sensor unit configured to generate at least two phase-shifted sensor signals which are dependent on the local electrical impedance of the film.

摘要： The invention relates to a measuring device for detecting absolution positions, comprising a sensor unit (N, M) as a planar coil structure and a scale having alternating areas of variable reluctance or conductivity along the measuring line. The invention is characterized in that the measuring device has at least two divisions (T1, T2) for determining the absolute position within the measuring length, the at least two divisions being coded aperiodically and in a bitwise manner and extending parallel to each other and, for each bit formation, having opposite effects on a coil element (S2, S3, S4) as part of the entire sensor structure. Preferably, each coil element (S2, S3, S4), comprising its own emitter and receiver windings (E, R), is balanced in offset, and the entire sensor structure provides approximately equal signal amplitudes for each individual bit of the absolute value at any position of the coded scale by means of compensation windings.
