Molten Alluminium  Thermocouples

Closely resembling to metal, PermAmelt is a new unique engineering ceramic. It is good choice as thermocouple protection tubes and immersed heater protection tubes for use in molten aluminum baths, even where there are rapid temperature fluctuations.

Due to impermeable and non-wetting surface of PermAmelt, the thermocouples assemblies need no daily washing or coating thereby proving use maintenance free use in molten aluminum baths, much longer than any other protection tube material.
PermAmelt thermocouple protection tubes require no preheating due to their low thermal expansion coefficient and thermal shock resistance.

Their low heat conductivity helps to prevent temperature drop in the molten aluminum bath and contributes to energy conservation. Since the tubes are of ceramic material, there is no iron pick-up to create inclusion in the aluminum
