Abstract

A pressure measuring unit includes a pressure measuring cell; a rotationally symmetrical sensor bushing into which the pressure measuring cell is inserted; a rotationally symmetrical process connection having, at one end, an inwardly extending encircling stop surface intended for the sensor bushing and, at another end, an opening for receiving the sensor bushing; a ring-like process seal between the sensor bushing and the stop surface of the process connection in order to thus prevent an ingress of the process medium into the pressure measuring unit; wherein the stop surface of the process connection and/or a counterpart stop surface, which in the installed state is directed toward the stop surface, of the sensor bushing have multiple individually formed webs configured such that the process seal is not extruded into the openings.
