摘要： A pressure sensor for measuring a pressure difference between a pressure being measured and the ambient atmospheric pressure surrounding the pressure sensor, including a platform and a membrane loadable with a pressure being measured. The membrane is secured at its edge to the platform, with a pressure chamber thus being formed between the platform and the measuring membrane. The pressure chamber communicates over a reference air path with the atmosphere, with the reference air path being a winding path.

摘要： A pressure gauge, or transducer, for high-temperature applications, comprising a sensor module with a sensor body having a measuring cell chamber containing a pressure measuring cell. The pressure measuring cell can be subjected to the action of a pressure via a first hydraulic path filled with a transmission liquid. The pressure gauge also comprises a transmission module for transmitting a pressure to the first hydraulic path. The transmission module has a second hydraulic path, which is filled with a transmission liquid and extends from a process diaphragm, through a transmission body and to a transmission diaphragm. The transmission diaphragm is attached to the transmission body in a pressure-tight manner, and the sensor body is joined to the transmission body in a pressure-tight manner, whereby the transmission diaphragm communicates with the first hydraulic path so that the pressure of the second hydraulic path can be transmitted via the transmission diaphragm to the first hydraulic path.

摘要： A pressure transmitter for transfer of a pressure prevailing in a first medium onto a second medium, including a pressure chamber 4 in a platform 1, which chamber is separated from the first medium by means of a dividing membrane 2, wherein the pressure can be transferred by means of the second medium to a pressure measurement cell. For timely recognition of an impending failure of the dividing membrane, an early warning detector is provided with a sensor chamber 6 having an opening, which faces the first medium; and a sensor 7, which monitors a property of a medium container in the sensor chamber; and a barrier facing the first medium, pressure-tightly sealing the opening, and which, under contact with the first medium and equal conditions as experienced by the dividing membrane 2, fails earlier than the dividing membrane, thus making possible a flow connection between the sensor chamber 6 and the first medium. Preferably, the barrier is in the form of a sacrificial membrane 5, which is thinner than the dividing membrane. In this way, it is to be expected that, under corrosive destruction of the membranes, the sacrificial membrane 5 will be destroyed earlier than the dividing membrane 2.

The hydraulic path contains a transfer liquid; a filling element, which is arranged in the transducer chamber, in order to fill hollow spaces between metal walls of the transducer chamber and the semiconductor pressure measuring transducer. An insulator plate, which is arranged in the transducer chamber between the measuring membrane and a wall of the transducer chamber lying opposite the measuring membrane; wherein the insulator plate is affixed to the filling element or is embodied as one piece with the filling element.
