ABSTRACT:
An adapter for pressure sensors for monitoring long-term cylinder pressures in internal combustion engines comprises a housing with a gas duct, a connection to a cylinder cover of an internal combustion engine, a rear opening of the gas duct from the housing with an apparatus for closing this rear opening in a gastight manner, and a connection for inserting a pressure sensor with a sensor membrane. The transition line of the opening in the gas duct, which is reached by the sensor membrane in the inserted state in order to be exposed to the gas pressure in the gas duct, is on a plane. The transition line forms the transition from the contour of the gas duct to the connection to the sensor. There is a continuous transition from the sensor membrane to the contour of the gas duct.
