Pressure sensor for detecting pressure in gas flow in fuel cell system utilized in vehicle for producing electric power, has membrane i.e. saucer-shaped membrane, arranged at guiding element, which comprises enclosed fluid

摘要

The sensor (1) has a membrane (3) i.e. saucer-shaped membrane, transferring pressure in to a region of a pressure transmitter (2) by enclosed fluid. The membrane is arranged at a guiding element (12), which comprises the enclosed fluid. The membrane is formed in the form of a hollow disk and is projected in to a medium (4) or a pipeline. A temperature sensor (13) is arranged at a region of the membrane and/or the guiding element. The membrane is arranged between the pressure transmitter and the medium, and a housing (5) of the sensor is seated on the pipeline.
