Abstract

A device for detecting a combustion chamber pressure of an internal combustion engine, in particular a gasoline engine. The device includes a sensor housing, the sensor housing being set up to be at least partially introduced into a combustion chamber of the internal combustion engine. At least one mechanical-electrical transducer element is accommodated inside the sensor housing, which is separated from the sensor housing by at least one sensor holder, in particular a sensor holder which at least partially encloses the mechanical-electrical transducer element. The sensor holder has an at least partially rigid design.
