Abstract

A pressure sensor assembly having a pressure tube, in which a diaphragm is situated as a pressure pickup, and having means for detecting the diaphragm deformations, which allow a spatial separation between the measuring medium acting on the diaphragm and the means for detecting the diaphragm deformations. The diaphragm of this pressure sensor assembly includes at least two diaphragm sections oriented at an angle to one another. A first diaphragm section is situated as a partition diaphragm in the cross-section of the pressure tube, while at least one second diaphragm section forms an area of the wall of the pressure tube as a side wall diaphragm. The means for detecting diaphragm deformations are situated on the outer side of the pressure tube on the side wall diaphragm.
