发明名称 DIFFERENTIAL PRESSURE TRANSDUCER
摘要 In a differential pressure transducer having isolation diaphragms on opposite sides of a sensing diaphragm, the isolation diaphragms are made highly compliant, are radially prestressed and are bowed outwardly relative to closely spaced backup surfaces by oil pressure. Using very small interior cavities and a substantially stiffer sensing diaphragm differential process pressures induce linear deflection of the sensing diaphragm.
