Silicon nitride thermocouple protection sheaths are an advanced ceramic tube offering outstanding performance for temperature control in aluminium foundries and smelters and are extremely cost effective compared to other materials, such as cast iron, silicon carbide and alumina.

Silicon nitride thermocouple protection sheaths or tubes are for use in the molten aluminium and non-ferrous industry.。

Thermocouple protection sheaths are used extensively for continuous temperature measurement in nonferrous metals.
