ABSTRACT:
A pressure sensor including: A pressure measuring cell having an end face loadable with the medium; a housing having a media opening and a ring-shaped, axial bearing surface, which surrounds the media opening; a clamping apparatus; and a ring-shaped sealing arrangement. The pressure measuring cell is positioned in the housing and the sealing arrangement is positioned between the bearing surface and the end face, and the sealing arrangement, as well as the pressure measuring cell, are axially clamped between the bearing surface and the clamping apparatus. The sealing arrangement includes, a decoupling ring, as well as a first and a second, ring-shaped sealing element. The first sealing element lies against the end face, the second sealing element lies against the bearing surface, and the decoupling ring is axially clamped between the first and the second sealing elements.
