Abstract:
A pressure transducer assembly comprising:(A) a first body including a case, one or more spokes, and a hub, said case having an interior surface, each of said spokes extending from a first end to a second end, the first end of each spoke contacting said interior surface, the second end of each spoke contacting said hub;(B) a second body;(C) a diaphragm mounted between said first body and said second body, said first body and said diaphragm defining a first chamber, said second body and said diaphragm defining a second chamber, a portion of said diaphragm flexing in a first direction in response to a pressure in said first chamber being higher than a pressure in said second chamber, said portion of said diaphragm flexing in a second direction opposite said first direction in response to said pressure in said second chamber being higher than said pressure in said first chamber;(D) an electrode disposed in said first chamber, said electrode being fixed to said hub, a capacitance between said electrode and said diaphragm being representative of a difference between said pressures in said first and second chambers.
