Abstract
A linear position sensing system with improved accuracy is shown. The sensor system has a magnetic field detector which senses the position of a target object. The target object has a magnet which emits a magnetic field. The position of the target object corresponds to the angle of the detected magnetic field. The linearity of the change in magnetic field angle is roughly proportional to the change in position of the target object. The magnet is magnetized on a slope which is determined by the path of traversal of the target object. In this manner, greater linearity in change of field angle relative to target object travel is achieved by altering the slope of the division between the magnetic poles.
