ANGULAR OR LINEAR MAGNETIC POSITION SENSOR NOT SENSITIVE TO EXTERNAL FIELDS

摘要

The sensor has bidirectional sensing heads (31, 32) comprising two sets of magnetosensitive elements that are respectively localized at a same point. The former set of elements is spatially moved from the latter set of elements along a displacement direction. One element from each set of elements measures a tangential component and another one element from each set of elements measures a normal component, of a magnetic field, for providing sinusoidal signals that are out of phase from 90 degrees, after algebraic combination of the components.
