  • Transducer circuit
    Patent number: 6505141
    Abstract: A position-to-electrical transducer circuit primarily intended for use in meteorological instruments for measuring a characteristic of a surface of a workpiece. An excitation signal generator provides to a transducer an excitation signal whose voltage varies in a known manner with time and a processor analyzes an electrical signal from the transducer to generate a measurement signal. The processor corrects for any phase shift between excitation signal and the electrical signal to provide an accurate measurement. A meteorological instrument for measuring a characteristic of a surface of a workpiece in which a pivotably-mounted arm holding a stylus is traversed relative to the surface of the workpiece and a variable transducer converts the position of the stylus into a corresponding electrical signal.
