ABSTRACT:
A pressure sensor for pressure detection in a combustion chamber of internal combustion engines of motor vehicles has a housing provided with an opening, a measuring element, a plunger arranged in the opening of the housing and having one end acting on the measuring element so that a measuring signal is produced proportionally to a pressure to be determined, the plunger directly abutting against the measuring element and having a material with a yielding point which is smaller than a breaking limit of a material of the measuring element, the end of the plunger which acts on the measuring element is spherical and abuts against the measuring element with such a contact surface that occurring stresses do not exceed a predetermined nominal value.
