ABSTRACT:
In order to prevent tilting and torsional stresses from entering the actual sensor element of a pressure sensor comprising a supporting part and an integrated sensor part, the proposal is put forward that the coresponding surfaces of a shoulder of the supporting part and of a fastening element screwed into the measuring bore be confugured as the lateral surfaces of cones whose generating lines intersect with the longitudinal axis of the supporting part, or as parts of the surface of a sphere whose center is situated on the longitudinal axis of the sensor part. The two corresponding faces transmitting the pressure from the fastening element onto the supporting part, and permitting a slight tilt of the longitudinal axis of the supporting part relative to the axis of the internal thread of the measuring bore.
