Abstract:
A pressure transducer assembly comprising:(A) a body defining an interior cavity, the body having a first portion;(B) a diaphragm mounted in the body and dividing the interior cavity into a first chamber and a second chamber, a region of the diaphragm moving in a first direction in response to a pressure in the first chamber being higher than a pressure in the second chamber, the region of the diaphragm moving in a second direction opposite the first direction in response to the pressure in the second chamber being higher than the pressure in the first chamber;(C) an insulating member disposed in the first chamber;(D) a conductor disposed on the insulating member, the conductor and the diaphragm being characterized by a capacitance, the capacitance being representative of a difference between the pressure in the first chamber and the pressure in the second chamber;(E) a compressed member disposed in the first chamber, the compressed member generating a force that biases the insulating member towards the diaphragm;(F) a support member disposed between the first portion of the body and a portion of the insulating member, the first portion of the body resisting movement of the support member towards the diaphragm and the support member resisting movement of the insulating member towards the diaphragm, the support member being characterized by a thickness and by a cross-sectional width, a ratio of the thickness to the cross-sectional width being greater than one.
