Abstract
A pressure measuring cell includes at least one ceramic measuring membrane body; and at least one ceramic platform, wherein the measuring membrane body is connected with the platform along an annular, peripheral joint. The joint is formed as a welded connection between the measuring membrane body and the platform, wherein the measuring membrane body has a pressure-dependently deformable measuring membrane. A pressure sensor includes a pressure measuring cell and a housing, wherein the pressure measuring cell is held by the housing, and wherein the pressure measuring cell closes a housing opening, through which the pressure measuring cell communicates with an environment of the housing. A seal is clamped between a sealing surface surrounding the opening of the housing and a sealing surface of the pressure measuring cell.
