Abstract

A position (11) sensor has magnetic sensors (3) between vertical magnets (1) and flat horizontal soft iron magnetic field modulators (2) arranged so that the processor output signal (3) depends on the modulation of the direction rather than the modulation of the value. Independent claims are included for dimensional measurement equipment using the position sensor.
