Title:
IMPROVED POSITION SENSOR
Document Type and Number:
WIPO Patent Application WO/2012/042154
Kind Code:
A8
Abstract:
The invention relates in particular to a method for parameterizing a system for measuring an absolute position, said system comprising a permanent magnet, at least one probe that is mobile relative to said magnet over a given path, and a calculation means providing position information calculated on the basis of the arctangent of the ratio, to which a correction coefficient G is assigned, between the output signals of the probe, wherein said signals are pseudo-sinusoidal and squared. Said method includes an optimization operation that involves selecting the value of the coefficient G that minimizes the errors of the measurement system resulting from the pseudo-sinusoidal character of the signals output from the probe.
