The Cerite-III unitized thermocouples are provided with a protection tube and integral thermocouple element with 36" of high temperature (1300 deg F) fiberglass leads, and a 1/2" NPT steel male face bushing for customer's use in mounting as standard. These Cerite-III thermocouples 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 2800 deg F, however its use as a Cerite-III thermocouple assembly is generally limited to 1500 deg F maximum. Protection tube pre-heating and slow immersion into the process is recommended.

Longer Lead lengths and Type J also available. Call for pricing and delivery.
