ABSTRACT:
A capacitive transducer indicates the value of a physical quantity to be measured and is constructed with two spaced electrically conducting plates movable relative to one another in response to a mechanical signal representative of the physical quantity to be measured to generate an electrical signal in response thereto with the transducer capacitor being actuated and de-actuated to be respectively responsive and non-responsive to the mechanical signal in accordance with pre-designated time intervals. The electrical signal in accordance with the capacitance of the transducer capacitor is integrated to provide an output signal when the integrated signal exceeds a reference value.
