  • Magnetostrictive position transducer with band passed mode converter output for rejecting mechanical noise
    Patent number: 5367255
    Abstract: A magnetostrictive linear position transducer of the type having an acoustic magnetostrictive waveguide for propagating acoustic pulses generated by the interaction of a permanent magnetic field with a periodic excitation magnetic field. The mode convertor for converting acoustic pulse into an electrical signal indicative of the passage of an acoustic pulse propagated pat the mode convertor location along the waveguide includes a passband type filter for improving the detectability of the acoustic signal.

  • Modular magnetostrictive displacement sensor having a waveguide protected by a material with a thermal coefficient of expansion the same as the waveguide
    Patent number: 5313160
    Abstract: A modular magnetostrictive displacement sensor is disclosed having a waveguide of magnetostrictive material extending from a first housing and protected by a member of fiber reinforced composite material. There is circuitry in the first housing for generating electrical pulses along the waveguide and a converter for generating an electrical signal in response to a torsion pulse in the waveguide caused by a magnet disposed proximate the waveguide when the electrical pulse passes the magnet position. In one embodiment the waveguide and its protective member is received within a second housing. One or more magnets may be mounted within the second housing or externally on or near the second housing for movement to the waveguide. Alternatively the sensor may be used without the second housing.

  • System and method for measuring the absolute position of one body which is constrained to move with respect to another body
    Patent number: 5115195
    Abstract: A system and method for measuring the absolute position of one body which is constrained to move with respect to another body includes a plurality of magnetic identification units, which are adapted to be mounted in a predetermined absolute position on a first body. Each of the magnetic identification units has an identity characteristic that is associated therewith. A Sensor having a transducer is adapted to be fixed to a second body. The transducer is adapted to sense (a) the relative distance of at least one of the magnetic identification units with respect to a benchmark location which is fixed relative to the transducer and the second body. It is also equipped to sense the identity characteristic of the sensed unit. A controller is provided to receive data representing the relative distance and identity characteristic of the sensed unit from the sensor.
