Measuring system for angular positions based on magnets uses a magneto-resistive sensor to detect permanent magnet field components in interlinked bridge circuits

摘要

Stemming from non-homogeneity in permanent magnets, an error of measurement can be reduced to a large extent upon adjusting a center point shift in two sensor signals by a value yielded from geometrically caused non-homogeneity in permanent magnets. An independent claim is also included for a method for determining offset adjustments to an angular-position measuring system.
