Abstract
The present invention concerns a metallic flat gasket with at least one sealing layer with at least one port, with a sensor layer corresponding to the ports being deposited on at least one surface of the sealing layer. This sensor layer consists of a compression protection layer and at least one break, in which a sensor element is at least partially installed.

Metallic flat gasket with at least one sealing layer with at least one port, for which a sensor layer (1,1′) corresponding to the ports is deposited on at least one surface of the sealing layer, with the sensor layer consisting of a compression protection layer (2,2′) and at least one break (3,3′), in which a sensor element (4,4′) is at least partially installed, and the sensor layer (1,1′) is arranged on the side of the cylinder head gasket facing the cylinder head (9) and/or the engine block (10).
Method for producing a single-layer or multi-layer cylinder head gasket with a sensor element, characterized in that a compression protection layer (2,2′) is deposited on the metal gasket in the direction towards the cylinder head (9) and/or the engine block (10), with the compression protection layer having at least one break (3,3′), in whose region the sensor element (4,4′) is attached by a frictional connection.
