  • Capacitive pressure transducer having reduced output error
    Patent number: 5959212
    Abstract: A fluid pressure sensor (10) having a capacitive pressure transducer (12) having a thin, relatively flexible ceramic diaphragm (14) mounted in closely spaced apart relation to a rigid ceramic substrate (16) by a glass annulus (18) mounted in a housing (46) having a port (46a) for fluid whose pressure is to be sensed to be received on an outer face of the diaphragm. An electronic circuit (50) is mounted in a chamber (38) formed between a connector (36) and an outer face (12b) of the substrate. A source capacitor plate (20) and source trace (20b) are printed on the diaphragm and a detect plate (22) and detect trace (22b) are printed on a substrate with a guard plate (28, 28', 28"; 30, 30") printed on both the diaphragm and substrate completely surrounding the source and detect plates and traces.
