Against the body for a pressure cell, the pressure measuring cell with such a counter-body and process for its preparation

A counter body 10 of glass for a pressure measuring cell with a measuring diaphragm 10, and at least one such counter body 20, wherein the measuring diaphragm 20 is joined at an operative pressure measuring cell with at least one such counter-body pressure-tight manner, has a planar rim portion for joining with the measuring diaphragm, the border area surrounding a recessed contour 21 which approximates the bending line of the measurement diaphragm 20 to support the measuring diaphragm in case of an overload, wherein the surface of the body The contour 21 is produced by a method for the plastic deformation of a glass body, wherein the glass body under vacuum which the glass body is heated does not support at least in a region on a support so that a plastic deformation of at least one unsupported portion by thermal sinking of the non- supported range occurs.
