  • Distance-frequency transducer
    Patent number: 4392383
    Abstract: The distance-frequency transducer includes a capacitor whose capacitance changes as a function of movement of one electrode relative to the other. The movement is controlled by the parameter to be measured, as, for example, the pressure in a pressure pickup. The capacitance determines the frequency of an RC oscillator. The output frequency of the oscillator can be calibrated directly in pressure units.
