Patent ID: 8371176

Claim:
A pressure sensor, comprising: a housing defining a fluid passageway, wherein the fluid passageway has a first end and a second end; a diaphragm having a first side and a second side, the first side of the diaphragm mounted adjacent to the second end of the fluid passageway of the housing; a carrier having a first side and a second side, and a first opening extending between the first side and the second side of the carrier, the first side of the carrier mounted adjacent to the second side of the diaphragm; a pressure sensing die mounted adjacent to the second side of the carrier, the pressure sensing die including a pressure sensing diaphragm that is in fluid communication with the first opening of the carrier; a transfer fluid cavity formed, at least in part, by the second side of the diaphragm, the first side of the carrier and the pressure sensing diaphragm of the pressure sensing die, the transfer fluid cavity having a height dimension defined between the second side of the diaphragm and the first side of the carrier, and a width dimension that is substantially perpendicular to the height dimension; a pressure transfer fluid disposed within the transfer fluid cavity; and wherein an aspect ratio of the height dimension to the width dimension of the transfer fluid cavity is less than 1:10.
