The Twin Bore Ceramic Thermocouple can be used at high temperatures. These are offered in aluminous porcelain for Type K and J thermocouples or as recrystallized alumina for type R and S thermocouples. It is possible to shorten by removing the insulators if one requires a particular length.
The product features of the twin bore ceramic thermocouple are:
Thermocouple types are K, J, R, or S
Ceramic sheath material includes Types K and J, Aluminous Porcelain rated to 1350ºC (K) and 750ºC (J) as well as Types R and S, Re-crystallised Alumina rated to 1700°C (R) and 1750°C (S)
Twin bore round insulators are used except in the case of 3.25mm diameter conductor models where oval insulators are used
A wide range of lengths and conductor diameters are available.
