Patent number: 9863830Abstract: A pressure sensor, including a platform of ceramic, a measuring membrane arranged on the platform, a pressure measuring chamber enclosed in the platform under the measuring membrane, and at least one metal body connected with the platform via a pressure-tight, preferably elastomer free, mechanical connection. Thermomechanical stresses arising from the connection are reduced by features including that the pressure-tight, mechanical connection occurs via an adapting body arranged between the platform and the metal body. The adapting body has a thermal expansion coefficient, which rises in direction (z) extending from the platform to the metal body from a coefficient of expansion corresponding to a thermal coefficient of expansion of the ceramic of the platform to a coefficient of expansion corresponding to the thermal coefficient of expansion of the metal body, and the adapting body is connected by a first joint with the platform and by a second joint with the metal body.Type: GrantFiled: December 18, 2014Date of Patent: January 9, 2018Assignee: Endress + Hauser GmbH + Co.

Patent number: 9625335Abstract: A pressure measuring cell includes at least one ceramic measuring membrane body; and at least one ceramic platform, wherein the measuring membrane body is connected with the platform along an annular, peripheral joint. The joint is formed as a welded connection between the measuring membrane body and the platform, wherein the measuring membrane body has a pressure-dependently deformable measuring membrane. A pressure sensor includes a pressure measuring cell and a housing, wherein the pressure measuring cell is held by the housing, and wherein the pressure measuring cell closes a housing opening, through which the pressure measuring cell communicates with an environment of the housing. A seal is clamped between a sealing surface surrounding the opening of the housing and a sealing surface of the pressure measuring cell.Type: GrantFiled: February 10, 2012Date of Patent: April 18, 2017Assignee: ENDRESS + HAUSER GMBH + CO.
