Title
(EN) Differential pressure sensor arrangement and associated differential pressure sensor
Abstract
(EN)

The invention relates to a differential pressure sensor array comprising a differential pressure sensor which is inserted in a receiving space in the direction of the longitudinal axis thereof. At least one sealing element that separates the receiving space into a first and a second pressure zone when the differential pressure sensor is inserted is disposed on the differential pressure sensor and/or in the receiving space. The first pressure zone is embodied entirely in an area located between a peripheral surface of the differential pressure sensor surrounding the longitudinal axis and an interior wall of the receiving space which faces said peripheral surface. At least one section of the first pressure zone extends only across a subarea of the peripheral surface in the circumferential direction. Also disclosed is an associated differential pressure sensor.
