Patent ID: 7316163

Claim:
A capacitance pressure transducer, comprising: a housing; a first conductor disposed on a face of the housing; a diaphragm, wherein a portion of the diaphragm moves in response to a differential pressure that is acting upon the diaphragm; a second conductor disposed on the diaphragm, the first and second conductors providing a capacitance, the capacitance being indicative of a gap that exists between a part of the diaphragm and the first conductor; and a seal disposed between a portion of the housing and a portion of the diaphragm, the seal including a first element that at least partially surrounds a set of spacer elements, the first element and the spacer elements being comprised of a glass material, the seal having a thickness which is substantially equal to a height of the spacer elements, the first element being characterized by a first melting temperature and the spacer elements being characterized by a second melting temperature, the first melting temperature being lower than the second melting temperature.
