Apparatus for sensing angular position |
摘要 |
An apparatus for sensing a position of an object is provided that may include a magnet having a set of magnetic flux properties, the magnet mounted for movement about an axis relative to the object and a magnetic field-sensing device mounted in fixed relation to and spaced from the magnet, the magnetic field-sensing device calibrated to sense a change in at least one magnetic flux property in response to movement of the magnet relative to the object and generate a data signal indicative of a position of the object. In one aspect the magnet is configured to have a substantially diamond shaped cross section and the magnetic field-sensing device is calibrated to sense a change in flux density distribution in response to a change in an air gap defined between an exterior surface of the magnet and the magnetic field-sensing device.
