ABSTRACT:
A sensor assembly is disclosed for measuring the position of a target object as it traverses a linear path of travel within a defined range of measurement. The sensor assembly comprises a ferromagnetic magnetic flux concentrator assembly. The flux concentrator assembly is configured as a generally u-shaped structure including a permanent magnet with elongated ferromagnetic flux concentrator elements affixed at the poles thereof and extending in substantially parallel fashion there from. A galvanomagnetic sensing element is disposed within an air gap between the free end portions of the flux concentrator elements and is displaceable along the longitudinal axis of the flux concentrator assembly. The galvanomagnetic sensing element is configured to provide an output signal indicative of the measured linear position as it travels along the longitudinal axis of the flux concentrator assembly.
