Abstract:
1. A pressure sensor measuring element for detecting pressure in a combustion space of an internal combustion engine, the pressure sensor measuring element comprising: a separating diaphragm; a plunger configured to transmit deflections of the separating diaphragm to a force measuring element; and a sleeve that is configured to receive the plunger and which is closed by the separating diaphragm at a first end arranged to face the combustion space, the sleeve being further configured to hold the force measuring element at a second end that is opposite to the first end; the force measuring element being configured as a flexural beam with a strain gauge, and the force measuring element being fastened at one end to the second end of the sleeve and at another end to an end of the plunger which faces away from the separating diaphragm; and the plunger being configured integrally with the separating diaphragm as a diaphragm/plunger unit, and the plunger, the sleeve and the diaphragm/plunger unit being formed from the same metal material.
