    摘要: The invention is concerned with a pressure sensor which avoids temperature hysteresis effects caused on account of heat-induced expansions as a result of stresses between a ceramic pressure-measuring cell and a metallic housing. The inventive pressure sensor (100) for determining the pressure of a process medium comprises a metallic housing (110), which is open to a process medium and has a continuous hole (111) for accommodating the ceramic pressure-measuring cell (120), the pressure-measuring cell (120) comprising a ceramic base body (122) and a ceramic diaphragm (121), which is fitted thereon and is exposed to the process medium, and also suitable means (124a, 124b, 130), which supply an electrical signal which can be picked off and corresponds to the process pressure acting on the diaphragm (121). The pressure-measuring cell (120) is fixed axially in a resilient manner in the housing (110) by means of a metallic fixing device (150) which acts on a non-metallic intermediate body (140), which is provided between the pressure-measuring cell (120) and the fixing device (150) and can be moved radially at least with respect to the fixing device (150).

    摘要: A method for operating a pressure sensor, which includes a measuring membrane, at least one platform and a capacitive transducer having two pressure dependent capacitances between electrodes on the measuring membrane. The measuring membrane divides a volume pressure-tightly into two volume portions, wherein the second volume portion is enclosed in a measuring chamber between the measuring membrane and the platform. A deflection of the measuring membrane depends on a pressure measurement variable p, which is a difference between a first pressure p1 and second pressure p2 in the volume portions. The pressure measurement variable p follows from both capacitances, wherein, for an intact pressure sensor, the second capacitance is a predetermined function of the first capacitance and, in given cases, the temperature. The method has steps as follows: registering value pairs of both capacitances; testing whether the value pairs correspond within a tolerance range to the predetermined function; and determining a change, respectively damage, of the sensor, when this is too long not the case.
