摘要:
The invention relates to a thermocouple system (1), comprising a metal feedthrough (2) having a cylindrical portion (10) having an axis of symmetry (S) and a terminal end region (11) arranged thereon, which completely closes the cylindrical portion (10), and which has at least two passageways (12), the opening cross-section of which is smaller than the cross-sectional surface (Q) vertical to the axis of symmetry (S) through the cylindrical portion (10). Through one passageway (12), a thermocouple (20) is guided, and in the region of the passageway (12), the thermocouple (20) is connected to the end region (11) in a fluid-tight manner by way of a seal (15).
摘要:
The invention relates to a heat shield element having at least one side wall (16), wherein the side wall (16) comprises at least one depression (4) having a passage (30) that points in the direction of a supporting structure (17), wherein a fixing screw (18) can be introduced into the depression (4) and can be led through the passage (30) for fixing the heat shield element (14) perpendicularly to a screw fixing means (19) provided on the supporting structure (17), wherein the passage (30) in the side wall (16) comprises a securing means (41, 42) which is at least partly formed by the side wall (16), and wherein the securing means (41, 44) prevents the fixing screw (18) falling laterally out of the passage (30) during installation.
