Abstract: A method for linearizing sensor signals in a magnetic strip length measuring system moves a sensor head between two magnetic poles of a measurement body. In particular, linearization takes place dynamically during operation of the magnetic strip length measuring system, and linearization deviations are compensated by extrapolation as the sensor head moves between the two poles of the measurement body from pole to pole or from pole pair to pole pair.

Abstract: A method for operating a magnetostrictive displacement measuring device, having a wave guide for guiding at least one mechanical wave, at least one damping zone, a magnetic position encoder which is displaceably arranged along a measuring range of the position measuring device and a detection unit, generates the at least one mechanical wave by an excitation signal (IP) having a clock frequency (f1, f2), at least two mechanical waves having respectively different clock frequencies (f1, f2, f) being generated. The clock frequencies can be predetermined such that interfering reflections (R11, R12) occur at different positions (x11, x21, x2) of the measuring range of the displacement measurement device, and during the method of the position encoder, switching between the different clock frequencies (f1, f2, f) takes place, such that the interfering reflections (R11, R12) on the respective different positions (x11, x21, x22) of the measuring range are masked out.

Abstract: In a length or position measuring system which has an at least locally substantially linear measuring gauge and at least one sensor to be moved relative to the measuring gauge, wherein the measuring gauge includes an incremental track and at least one absolute track and wherein the incremental track and the at least one absolute track have poles arranged in the longitudinal direction of the measuring gauge, the poles of the at least one absolute track form at least two regions in the sensor with different field strengths or signal amplitudes.
