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 suppression of switching power supply noise

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.

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.
