Abstract

The disclosed pressure transducer assembly includes a first body, a second body, a diaphragm, and an electrode. The first body induces a case, one or more spokes, and a hub. The case has an interior surface. Each of said spokes extends from a first end to a second end. The first end of each spoke contacts the interior surface and the second end of each spoke contacts the hub. The diaphragm is mounted between the first and second bodies. The first body and the diaphragm form a first chamber. The second body and the diaphragm form a second chamber. A portion of the diaphragm flexes in a first direction in response to pressure in the first chamber being greater than pressure in the second chamber. A portion of the diaphragm flexes in a second direction, opposite the first direction, in response to pressure in the second chamber being greater than pressure in the first chamber. The electrode is disposed in the first chamber and is fixed to the hub. A capacitance between the electrode and the diaphragm is representative of a difference between the pressures in the first and second chambers.
