Types of molten metal thermocouples



molten aluminum thermocouple
These are used for molten aluminium metal temperature measurements in melting and holding furnaces. The material was developed for use in molten non-ferrous metals, specifically molten aluminum . It has excellent non-wetting properties, allowing easy slag removal, and the small diameter provides fast thermal response to process temperature changes. These assemblies provide good resistance to thermal shock and mechanical breakage.



molten zinc thermocouple
These are specially developed metallic sheath to withstand the erosive nature of liquid Zinc. Recommended for continuous dipping. All assemblies are supplied with die cast aluminium terminal heads and high purity ceramic terminal blocks. Ungrounded (isolated) hot junction as standard. Assemblies may be dispatched with the hot arm unattached for assembly at the time of installation due to size limitations.




silicon nitride molten metal thermocouple
world renowned for their outstanding performance in contact with non-ferrous molten metals, particularly aluminium and its alloys and zinc. They allow constant temperature monitoring of the melt resulting in improved quality of the finished casting. In addition to its excellent physical properties and is is also non-wetting to most non-ferrous alloys, making it resistant to build up of dross and is therefore very low maintenance.
For high temperature applications above 1200°C, . Again offering outstanding physical properties, can be used be at temperatures up to 1400°C.




Single-Use molten metal thermocouple
Expendable, single-use, and high precision thermocouple tip. It is suited for a wide range of molten metals - Iron, Steel, Copper, Bronze, and Aluminum. thermocouple tips are constructed from convolute paper tubes with a ceramic body thermocouple insert and moisture-resistant cement for accurate and quick temperature measurement. They have a slower burn rate and greater beam strength than spiral paper tubes. The small-diameter tube is designed for easy penetration in furnaces or ladles.
Additional non-splash, for improved operator protection, together with multi-immersion designs are available for critical applications and use in foundries.



Handheld molten metal thermocouple
Dipstick Thermocouple are used for measuring the temperature of non-ferrous molten metals; the swaged thermocouple element will endure up to 1000 cycles into a melt but this will vary with different types of metal and slag conditions. When the thermocouple element begins to degrade it can be replaced easily and wired into the plastic handle
