Abstract
The present invention provides an apparatus and a method for determining the position of a first element relative to a second element. The apparatus includes a magnet being attached to the first element. First and second sensing devices are adapted to detect a magnetic flux density produced by the magnet and responsively generating first and second signals. The apparatus also includes a controller for receiving the first and second signals and responsively determining the position of the first element relative to the second. The present invention enables continuous calibration during the normal operation of the machine.
