Method for temperature compensation for the output of an angular position sensor

摘要

A method for compensating the output of an angular position sensor assembly includes placing a first magnetic field sensor such that it is oriented ninety degrees from a second magnetic field sensor. A magnet is placed so that it is equidistant from the sensors. The magnet is rotated, and as it rotates, the signals output by the sensors are sinusoidal waves that are out of phase with each other by ninety degrees (90°). Accordingly, the signals can be squared and summed to determined a temperature compensation signal.
