Cerite® III thermocouple assemblies are complete thermocouple and protection tube assemblies.
These Cerite® III assemblies are constructed by casting a phosphate bonded refractory material containing 85% alumina, 4% silica, and other trace elements around a 1/4" NPT steel pipe containing an integral stainless steel sheathed magnesium oxide (MgO) insulated thermocouple element.
The cast refractory material was developed for use in molten non-ferrous metals, specifically molten aluminum and zinc. It has excellent non-wetting properties allowing easy slag removal, and the small diameter provides fast thermal response to process temperature changes.
These assemblies also provide good resistance to thermal shock and mechanical breakage.
The refractory material is rated at 1,538º C [2,800º F] however its use as a Cerite® III thermocouple assembly is generally limited to 815º C [1,500º F] maximum. Cold leg as standard is supplied as carbon steel.
