Thermocouple system with endständigemAbschlussbereich

The invention relates to a thermocouple system (1) comprising a metal bushing (2) with a cylindrical portion (10) having an axis of symmetry (S) and a disposed thereon terminal closure region (11) connecting the cylindrical portion (10) closes completely, and at least two passages (12) whose opening cross section is smaller than the cross-sectional area (Q) perpendicular to the axis of symmetry (S) through the cylindrical portion (10), through a passage (12), a thermocouple (20) is guided and the thermocouple (20) in the region of the passage (12) with the end region (11) fluid-tight manner by a closure (15) is connected.
