Abstract
A pressure sensor measuring element for a pressure sensor operates to detect pressure in a combustion space of an internal combustion engine. The pressure sensor measuring element includes a separating diaphragm, a plunger for the transmission of deflections of the separating diaphragm to a force measuring element, and with a sleeve which receives the plunger. The sleeve is closed by the separating diaphragm at a first end intended to face the combustion space and is designed to hold the force measuring element at the opposite second end. Accordingly, the pressure sensor measuring element can be produced more cost-effectively. Furthermore, the plunger can be produced in one piece with the separating diaphragm as a diaphragm/plunger unit, and the sleeve and the diaphragm/plunger unit can be formed from the same metal material.
