(DE) Differenzdrucksensor-Anordnung und zugehöriger Differenzdrucksensor
(EN) Differential pressure sensor assembly and associated differential pressure sensor
(FR) Dispositif capteur de pression différentielle et capteur de pression différentielle associé
Abstract
(EN)
The assembly has a differential pressure sensor (12), which is inserted toward an longitudinal axis (X) into an area (4), where at the differential pressure sensor and or in the area a seal element (32) is provided. The seal element divides the area with assigned differential pressure sensor into two pressure zones. The first pressure zone is between the longitudinal axis and a surrounding surface of the differential pressure sensor. An inner wall of the area is a section of the first pressure zone in circumferential direction extending over a subrange of the surface.
