  • Patent number: 11846555
    Abstract: Disclosed is a pressure gauge comprising a pressure sensor and a pressure transmitter connected upstream of the pressure sensor and having an isolation diaphragm enclosing a pressure receiving chamber. A hydraulic pressure transmission path is connected to the pressure receiving chamber and is filled with a pressure transmitting fluid that transmits the pressure acting on the outer side of the isolation diaphragm to the pressure sensor The pressure gauge allows functional impairments of the pressure gauge to be detected early without having to change the pressure acting on the outer side of the isolation diaphragm. The pressure transmitter comprises an electronically activatable deflection device which is designed in such a way that, when activated, it exerts a constant force deflecting the isolation diaphragm, on the isolation diaphragm, or on an element connected to the isolation diaphragm.

  • Patent number: 9470773
    Abstract: 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.
