Abstract (en)

[origin: WO2008012162A1] Disclosed is a dry front-flush pressure measuring sensor which can take reliable measurements within a great temperature range and comprises a process connection (1, 1a, 1b) that is made of stainless steel and is used for fastening the pressure measuring sensor to a measuring point, and a pressure sensor module (3, 17, 29, 41). Said pressure sensor module (3, 17, 29, 41) is provided with a stainless steel fixture (5, 19, 31, 43), into which a metallic separating membrane is inserted in a front-flush manner by means of a purely metallic connection, a pressure (p) that is to be measured being applied to the external face of said separating membrane. The fixture (5, 19, 31, 43) is inserted in a front-flush manner into the process connection (1, 1a, 1b) by means of a purely metallic connection. The pressure sensor module (3, 17, 29, 41) is also provided with a round titanium plate (7, 27, 53) which is supported by the fixture (5, 19, 31, 43) and to which a sapphire support (13) is applied that is fitted with silicon sensors (15) introduced thereinto. The round titanium plate (7, 27, 53) forms the separating membrane (7) or is mechanically connected to the separating membrane (23, 35, 51) in such a way that a deflection of the separating membrane (23, 35, 51) causes the round titanium plate (27) to be deflected in a corresponding fashion.
