ABSTRACT:
An apparatus is provided for determining the position of a shaft that is rotatably displaceable about a longitudinal axis. The apparatus includes a magnet, first and second magnet-detecting devices that are arranged adjacent the shaft, and a third magnet-detecting device mounted on the shaft. A rotatably displaceable disk having the magnet mounted thereon is arranged to allow the magnetic field produced by the magnet to pass over and activate each of the magnet detection devices sequentially. A position-determining circuit connected to the magnet-detecting devices, measures the time interval that the magnet-detecting devices are sequentially activated by the magnetic field and applies the time so measured to a position-determining scheme. The position-determining scheme uses the time measured and the physical geometry of the apparatus to determine the position of the shaft.
