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.
