Abstract
A tube skin thermocouple assembly and method of making same, characterized by a sheathed thermocouple cable having an angularly disposed sensing end terminating in an end face extending substantially parallel to the axis of the adjacent axial portion of the sheath. A measuring junction of the conductors is formed in an end cavity in the sensing end substantially free of insulating material and filled with filler metal embedding the measuring junction therein, the filler metal thus providing an end closure having an exposed face substantially flush with the end face and forming therewith a contact face adapted for contiguous intimate contact with a tube surface. The end closure may be of a large mass of filler metal for direct welding of the sensing end of the assembly to the tube, and the contact face may be either flush with or slightly offset from the outer diameter of the adjacent axial portion of the sheath, respectively, for flush or radially spaced axial mounting of the assembly on the tube. Alternatively, where the contact face is flush with the outer diameter of the adjacent axial portion of the sheath, the sensing end may be removably mounted by a strap welded to the tube …
