  • Magnetostrictive displacement transducer with suppression of switching power supply noise
    Patent number: 8427137
    Abstract: A transducer senses repetitive pulses on a magnetostrictive element and provides transducer output bursts. A transducer circuit detects the transducer output bursts. An energy storage device couples to a power input of the transducer circuit. A switching power supply couples to the energy storage device and has repetitive suppressed states during which switching in the switching power supply is suppressed. A sequence circuit provides synchronization of the repetitive suppressed states of the switching power supply with the transducer output bursts.

  • Magnetostrictive displacement transducer with phase shifted bias burst
    Patent number: 8054066
    Abstract: An assembly includes a magnetostrictive transducer that provides a transducer output. Amplifier circuitry receives the transducer output and generates a transducer output burst and a bias output burst. The transducer output burst and bias output burst overlap in time and differ by a phase difference. A burst processor receives the transducer output burst and the bias output burst. The burst processor provides a displacement output that is a function of a time when the transducer output burst and the bias output burst are at the same voltage level.

  • Magnetostrictive elongation sensor
    Patent number: 8035372
    Abstract: A magnetostrictive position or elongation sensor of the type in which an elongated magnetorestrictive waveguide is influenced by a magnetic field from a moving magnet has a Villary type transformer at one end and a hermetically sealed housing containing the signal processing circuitry on a plurality of circuit boards. The signal processor can switch the sensor into a programmable mode in which a diagnostic output is obtained recognizing the magnet, the presence of the sensor in the programming mode and voltage values.
