发明名称 Digital signal output capacitance sensor displacement gauging system
摘要 A new variable impedance type system is described for measuring a preselected physical parameter such as spacing, displacement, pressure, vibration, etc. A sensor/transducer is positioned to provide the variable impedance. The sensor/transducer is part of a self-oscillatory circuit which produces pulses having a pulse rate proportional to the physical parameter being measured.
