Measurement device for detecting processes in combustion chamber of internal combustion engine, has pressure sensor with optical light cable ending in combustion chamber, where optical coupling element is soldered in pressure membrane

摘要

The measurement device (1) has a pressure sensor (3), which is formed for inserting in a bore opening in a combustion chamber of an internal combustion engine. The pressure sensor has an optical light cable (6) ending in the combustion chamber, where an optical coupling element (8) is arranged in the opening area in the combustion chamber. The optical coupling element is soldered in a pressure membrane (5) of the pressure sensor or in a housing (2) of the pressure sensor.
