摘要： A rotary position sensor measures the relative angular position (within a range of≦180°) of a housing or stator and a rotor. The housing carries a galvanomagnetic sensing element and is adapted for fixation to a relatively fixed portion of a host system. The rotor carrying a magnet is disposed for rotation about a fixed axis with respect to the stator and is interconnected to a relatively moving portion of the host system through intermediate linkage. The magnet is juxtaposed in substantially axial alignment with the galvanomagnetic sensing element for magnetic interaction therewith. The housing defines a cavity to receive potting material for encasing the galvanomagnetic sensing element and an adjacent buffer cavity interconnected by a weir, which diverts ant excess potting material into the buffer cavity.

摘要： An apparatus for sensing a position of an object is provided that may include a magnet mounted for rotation about an axis and a magnetic field-sensing device mounted in fixed relation to and spaced from the magnet wherein the magnet is shaped to define a distance between an exterior surface of the magnet and a surface of the magnetic field-sensing device whereby rotation of the magnet causes the distance to change at a rate so that a flux density distribution sensed by the magnetic field-sensing device changes at a substantially linear rate. In one aspect the magnet is configured to have a substantially elliptical shape and the magnetic field-sensing device is a Hall-effect sensor. A sensor system may include a housing, a magnet having an exterior surface defining a radius of curvature and a shaft rotatably coupled with the housing with the magnet connected to the shaft for rotation about an axis in response to an angular displacement of an object. A magnetic field-sensing device may be provided that is coupled with the housing and spaced from the magnet to define an air gap there between. The air gap may change at a rate in response to rotation of the magnet so that a flux density level sensed by the magnetic field-sensing device changes at a substantially linear rate.

摘要： A sensor assembly is disclosed for measuring the position of a target object as it traverses a linear path of travel within a defined range of measurement. The sensor assembly comprises a ferromagnetic magnetic flux concentrator assembly. The flux concentrator assembly is configured as a generally u-shaped structure including a permanent magnet with elongated ferromagnetic flux concentrator elements affixed at the poles thereof and extending in substantially parallel fashion there from. A galvanomagnetic sensing element is disposed within an air gap between the free end portions of the flux concentrator elements and is displaceable along the longitudinal axis of the flux concentrator assembly. The galvanomagnetic sensing element is configured to provide an output signal indicative of the measured linear position as it travels along the longitudinal axis of the flux concentrator assembly.

摘要： A sensing assembly senses varying parameters of a bearing mechanism. The bearing mechanism includes a circular bearing housing. The sensing assembly includes a sensor case. The sensor case is fixedly secured to the bearing mechanism. The sensor case includes a peripheral surface and a top plate with extensions protruding outwardly therefrom. The sensing assembly also includes a sensor housing that is removably insertable into the sensor case. The sensor housing selectively engages the extensions of the sensor case to secure the sensor housing in the sensor case at a location spaced from the bearing mechanism. The sensing assembly includes a sensor that is disposed within the sensor housing. The sensor senses the parameters of the bearing mechanism, wherein the sensor and the sensor housing may be removed from the bearing mechanism and replaced without replacing the bearing mechanism. The extensions may be bosses that have channels allowing heat stakes to extend therethrough or, in an alternative arrangement, the extensions may be notches that receive latches therein to removably lock the sensor in place.
