PCT No. PCT/DE91/00523 Sec. 371 Date Mar. 3, 1992 Sec. 102(e) Date Mar. 3, 1992 PCT Filed Jun. 27, 1991 PCT Pub. No. WO92/01912 PCT Pub. Date Feb. 6, 1992.A pressure sensor for detecting pressure in a combustion chamber of internal combustion engines has a housing, a sensor element arranged in the housing and composed of a piezoresistive material, a diaphragm, and a punch arranged between the diaphragm and the sensor element and introducing a pressure to be determined onto the sensor element. The punch has an end facing the sensor element, at least the end of the punch is composed of relatively soft material.
