Beschreibung
Zusammenfassung:	A pressure sensor for measuring pressures in combustion chambers of internal combustion engines includes a sensor housing with a longitudinal axis and an interior space, a measuring element in the interior space, and a rotation-symmetrically designed membrane with a peripheral edge section connected with an end of the sensor housing at the pressure chamber side to seal off the interior space of the sensor housing on the pressure chamber side. The membrane has a flexible annular membrane segment and a central plunger that interacts with the measuring element and the flexible annular membrane segment. The annular membrane segment connects the plunger with the peripheral edge section. The annular membrane segment is designed as a convex circular arc of constant material thickness on the pressure chamber side.
