DRUCKSENSOR MIT EINEM KERAMISCHEN GRUNDKÖRPER
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.
