Abstract: In order to transmit data from an absolute position measurement system to an incremental interface, the transmission of an absolute position is carried out in a virtual reference journey of a position counter (cnt) via several phase-shifted electrical signals. During the virtual reference journey, at least one further information is transmitted in addition to the absolute position. For this purpose, a correspondingly designed absolute measurement system and a computing device are used, the computing device being designed to receive and evaluate data via an incremental interface.

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: 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.

Abstract: In a length or position measuring system which has an at least locally substantially linear measuring gauge and at least one sensor able 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 pole pairs arranged in the longitudinal direction of the measuring gauge, it is provided in particular that at least one pole pair of the absolute track is phase-shifted relative to a corresponding pole pair of the incremental track.
