  • Capacitive pressure sensor
    Patent number: 4864463
    Abstract: A dual capacitive pressure sensor includes matched variable capacitors which are immune to vibration and acceleration, but which respond equally to changes in external fluid pressure level. The structure of the sensor is configured to avoid calibration drift as the sensor ages, as well as to provide electrical shielding for the variable capacitors of the sensor.

  • Compensated pressure transducer
    Patent number: 3962921
    Abstract: A pair of diaphragms with substantially equal natural frequencies are superposed for movement in phase and in unison under accelerating forces, with electrical capacitor plates deposited on adjacent surfaces which provide an electrical measure of the differential diaphragm stressing with one of the diaphragms subject to a fluid pressure differential.
