In order to prevent electrical connection as well as the junction box body thread connection eroded by the harmful atmosphere, this product uses stainless steel explosion-proof connecting box. Its protecting tube uses the special sleeve fastening armored temperature measurement component, forms absolutely sealed structure. to prevent outer pipes leakage of oil or gas after abrasion,

  There are two structures and different materials to choose for the tubes. One is alloy tubes with different materials and spray coating Ni60WC40 outside as requested  . Another adopts overall drilling corrosion proof and heat proof alloy materials as the anti-wear head (tube). 

  This series of products is suitable for the temperature measurement of production process where certain speedy solid particle, liquid or gas is generated. It’s indispensable for the temperature measurement of circulative vulcanization bed (CFB), incinerator and oil refine factory.
