Rare metal thermocouples are used in applications where the temperatures exceed the working range of base metal thermocouples, i.e. 0â€1300°C, or where greater accuracy is required such as in standard thermocouples. Wire size is typically 0.5mm diameter.
SPECIAL PROTECTION SHEATHS
HEXOLOY® / SYALON®
Rare Metal Thermocouples require protection sheaths to avoid contamination from the process. Details of these are shown in the table below:
Note: LTâ€1, Sillimanite, Silicon Carbide, Hexoloy® and Syalon® require an inner, impervious sheath. Specific details of each of the above are available on request.
The above only cover the most commonly supplied thermocouples. We specialise in madeâ€toâ€order units, and will quote against your specifications.
