Abstract
A capacitive pressure transducer having a first flexible electrically insulative diaphragm disposed apart from a second electrically insulative member, including a second flexible diaphragm, and where the diaphragm and member include metalized portions thereon forming the plates of a pressure sensing capacitor. The transducer further includes a pair of electrically insulative sealing rings disposed concentrically about one another which function to space said diaphragm and member apart and which form a hermetically sealed cavity therebetween, to establish the pressure sensitive region of the diaphragm and to reduce the tensile forces in the inner most sealing ring.
