LINEAR SEGMENT OR REVOLUTION COUNTER WITH A FERROMAGNETIC ELEMENT

摘要

Absolute counter for linear segments or revolutions with a Wiegand element (WE) in the main field between two opposing excitation magnets (EM1, EM2) connected by a common ferromagnetic yoke body (14) and an additional sensor element (SE), for determining information about the polarity and position of the excitation magnets, wherein the output signals from the Wiegand element (WE) simultaneously provides the power for the required counter and memory circuits and an auxiliary sensor (ZS) for fine resolution in a multi-turn, which is also arranged in the main field between the excitation magnets (EM1, EM2).
