High Temperature Ceramic Thermocouple Sensor. These thermocouples are used for temperature measurement to 1600ºC plus in kilns, furnaces and flues etc. Available in thermocouple types K with an impervious aluminous porcelain sheath or type R and S with an impervious recrystallized alumina sheath, they have a stainless steel support tube attached to a weatherproof connection head.
Thermocouple types K , R or S
Ceramic sheath material:
Types K Aluminous Porcelain rated to 1350ºC (K)
Types R and S, Recrystallized Alumina rated to 1600ºC
Terminated in an IP67 weatherproof die cast alloy head rated to 135ºC
