Abstract
The capacitance type pressure transducer is disclosed which includes an isolation additional diaphragm made of the same material as the operative diaphragms the transducer. Material may be quartz, silicon, or aluminosilicate. The isolation diaphragm minimizes deflections of the operative diaphragms as the housing base is bowed due to the pressure differential between the internal reference pressure of the capsule and the ambient pressure. The transducer may be configured to measure an absolute pressure or a differential pressure.
