This heavy duty thermocouple is specifically designed for temperature sensing in arduous industrial environments such as blast or carburizing furnaces, kilns, large ovens and galvanising baths where their robust construction ensures a prolonged sensor life.

 

Available in thermocouple types: K, T, J, N, E, R, S, B, C, and Pt100.

Thick wall protective sheaths in stainless steel

 

Platinum rhodium thermocouple(S B R TYPE)

 

1.Platinum Rhodium Assembling Type Thermocouple is widely used in production places with high temperature. It is mainly used to measure temperature in glass and ceramic industry and industrial salting furnace.

 

2.Product Introduction 

 

 

Special thermocouple is made of noble metal,( platium in high purity as cathode, Platium and Rhodium alloy as positive pole), corundum as external tube, which is used to measure as high as 1800°C like powder metallurgy,fritting furnace,vacuum furnace, matallurgy furnace and calcination of fire-proof materials, proclein, ceramics.
