FLUID-FILLED PRESSURE SENSOR ASSEMBLY CAPABLE OF HIGHER PRESSURE ENVIRONMENTS

摘要

This disclosure provides systems and methods for a fluid-filled pressure sensor assembly for higher pressure environments. A fluid-filled pressure sensor assembly may be adapted for coupling to a structure at a mating surface and may include a header; a pressure sensor coupled to the header; a diaphragm coupled to the header and configured for positioning forward of the mating surface so that a fluid region is disposed between the diaphragm and the pressure sensor; a fill hole coupled to the fluid region; a sealing element coupled to the fill hole and configured for positioning forward of the mating surface; and wherein during operation the first pressure applied at the diaphragm is substantially transferred by the fluid in the fluid region and the fill hole to an inner-side of the sealing element and the first pressure is about equivalent to a second pressure applied at an outer-side of the sealing element.

1. A fluid-filled pressure sensor assembly adapted for coupling to a structure at a mating surface, comprising:
a header; a pressure sensor coupled to the header; a diaphragm coupled to the header and configured for positioning forward of the mating surface so that a fluid region is disposed between the diaphragm and the pressure sensor, wherein a first pressure applied at the diaphragm is transferred by a fluid in the fluid region to the pressure sensor for measurement thereof; a fill hole coupled to the fluid region, wherein the fill hole is used to fill the fluid region with the fluid; a sealing element coupled to the fill hole and configured for positioning forward of the mating surface, wherein the sealing element is used to seal the fluid in the fluid region and the fill hole; and wherein during operation of the fluid-filled pressure sensor assembly, the first pressure applied at the diaphragm is substantially transferred by the fluid in the fluid region and the fill hole to an inner-side of the sealing element and the first pressure is about equivalent to a second pressure applied at an outer-side of the sealing element.
