ABSTRACT:
A magnetic position sensor for measuring a position of a ferromagnetic target over a range. The sensor comprises a magnet at least as long as the range and a sensor array mounted upon a surface of the magnet. The array is at least as long as the range and includes a plurality of sensing elements mounted a fixed distance from the surface of the magnet. The magnet length and the fixed distance have values such that a set of relatively constant values, preferably values of magnetic flux density, is measurable in the sensor array in the absence of the ferromagnetic target. A method of making a position sensor is also disclosed, as is a method of measuring the position of a ferromagnetic target over a range.
