摘要： A pressure sensor module, comprising: a pressure measuring cell; and a mounting ring. The pressure measuring cell includes a platform and a measuring membrane, whose front face extends parallel to the rear face of the platform. The mounting ring has a mounting passageway with an inner mounting surface, which defines an inner axial stop plane for mounting the pressure measuring cell, wherein the mounting ring has an outer mounting surface, and the pressure measuring cell is inserted with the rear face preceding into the mounting passageway. The rear face of the platform is adhered with the inner mounting surface, wherein the inner mounting surface has a shoulder, which extends from an inner lateral surface of the mounting ring radially inwards. The mounting surface has between the axial stop surface and the inner lateral surface an annularly surrounding recess, in order to accommodate excess adhesive in the case of the adhering of the axial stop surface with the rear face of the platform.

摘要： A pressure transfer module for transfer of pressures, less equals 100 mbar, and suitable for high temperature applications, comprising an isolating diaphragm outwardly sealing a first pressure chamber; a transfer diaphragm outwardly sealing a second pressure chamber; and a pressure transfer path connecting the first pressure chamber with the second pressure chamber. The first and the second pressure chambers and the pressure transfer path are filled with a pressure transfer liquid, via which a pressure acting externally on the isolating diaphragm is transmitted to the transfer diaphragm. The pressure transfer liquid is under a pre-pressure, especially a pre-pressure of greater than or equal to 30 mbar, especially greater than or equal to 50 mbar. The isolating diaphragm and the transfer diaphragm under the pre-pressure assume a starting position, from which they are deflected by the pressure to be transmitted, and the starting positions of isolating diaphragm and transfer diaphragm lie as a function of size of the pre-pressure and size of the pressure to be transmitted within deflection ranges of the diaphragms, in which deflections from their starting positions have due to their formation a non-axisymmetric part, especially an antisymmetric part.

摘要： A pressure-measuring sensor having an electrically-conductive separating diaphragm closing off an interior chamber of the pressure-measuring sensor to the outside, to whose exterior surface a liquid medium under pressure can be applied, and having a device for detecting a diaphragm rupture of the separating diaphragm. At least one electrode is arranged on an interior surface of the separating diaphragm which faces the interior chamber, said electrode being electrically insulated from the separating diaphragm by an insulating layer arranged between the electrodes and the separating diaphragm and mechanically connected to the separating diaphragm, a measuring circuit is connected to a capacitor formed by the separating diaphragm and the electrode, said measuring circuit measuring and monitoring a measured variable dependent upon an electrical property of the capacitor, which is changed by a medium penetrating into the area of the capacitor when a diaphragm rupture of the separating diaphragm occurs.
