    摘要： A thermocouple is joined to a coaxial lead cable by a separable connector. The cold thermocouple junctions are formed at the connector, which comprises a sleeve, a nut having male threads, and a fitting having a cavity with mating female threads. The fitting is attached to the thermocouple tube so the thermocouple inner wire extends into the cavity, and the sleeve is attached to the outer conductor of the lead cable, so the inner conductor of the lead cable extends through the sleeve. The nut fits around the base of the sleeve. As the nut is screwed into the fitting, it forces the end of the sleeve to seat on a shoulder formed in the cavity of the fitting, thereby sealing the interior of the tube and the cable at their junction from the atmosphere. The electrical connection between the thermocouple inner wire and the inner conductor of the lead cable has limited longitudinal freedom of movement to accommodate for variations in the sleeve seating required to form the seal.

    摘要： A THERMOCOUPLE CONSTRUCTED BY HEATING A THERMOJUNCTION WELD AND AN ADJACENT SUPPORT MEMBER WITH EITHER A HYDORGEN-OXYGEN TORCH OR A "HELIARC" WELDING DEVICE UNTIL THE WELD IS MELTED INTO THE HOLES IN THE SUPPORT MEMBER OR UNTIL THE WELD PENETRATES THE HOLES OF THE SUPPORT MEMBER AND THE SUPPORT MEMBER PARTIALLY OR TOTALLY ENCAPSULATES THE WELD.
