The noble-metal thermocouple assemblies illustrated on this page are provided with double protection tubes. Outer protection tube choices of ceramic, metal alloys, or composite materials offer protection from a variety of high temperature process environments. All assemblies are provided with a ceramic inner tube. The inner tubes are cemented to the outer tube and are not replaceable, except for 18J assemblies. These assemblies are available with a variety of process mounting fittings and assembly options as listed below. Special construction designs are also available. Note: Welded bushings will be welded at maximum length possible when X and U dimensions are specified as the same length. Actual U dimension will be 1 to 2 inches shorter than specified depending on bushing size.
