DIAPHRAGM ASSEMBLY FOR A PRESSURE SENSOR, AND A PRESSURE SENSOR PROVIDED WITH SUCH ASSEMBLY

摘要

Diaphragm assembly for a pressure sensor, comprising a multi-layered assembly of an outer diaphragm and an inner diaphragm, and an intermediate layer between both diaphragms, the intermediate layer being made of a solid material which is permeable to air. Pressure sensor comprised of an assembly of: a diaphragm seal body, having a diaphragm side which comprises a chamber for containing a pressure measuring fluid, and a channel designed for connecting the chamber to a measuring device; a mounting body which is at an inner side designed for assembling to the diaphragm side of the diaphragm seal body, and at an outer side is designed for mounting the sensor to external equipment of which an external pressure is to be measured; a diaphragm assembly, fixed between the diaphragm side of the diaphragm seal body, and the inner side of the mounting body, and wherein the diaphragm seal body and the mounting body are assembled to each other by coupling means.
