Thermocouple Refractory Tubes

Assemblies | Floats | Elements | Tubes

Applications

Refractory tube thermocouples have a fiber and cement laminate for protection. They very work well in molten Zinc and Aluminum. The laminate coating will not contaminate the molten metal. Tips are made from Silicon Carbide for fast response. Thermal shock resistant.

Construction

Refractory thermocouple tubes and floats are available with or without a thermocouple element. The elements are Type K. Thermocouples and floats also have 36" of leads. Flexible leads have fiberglass insulation Tubes have a 3/4" NPT instrument thread.
