Brief Description

The WRNN-430 wear resistance thermocouple adopts different strength wearresistance protection tube due to different temperature ranges and medium whichconstitute compound tube type solid structure, thus it’s applicable tooccasions which may cause heavy wear like petrochemical industry, coaltransmission system, fluidized bed boiler, cement clinker and fire-proofmaterial etc.

The WRNN-430 wear resistance thermocouple from our company is ofinternational level with advanced technology, the special wear resistancematerial guarantee its long-service life (1~2 years) without influence onmeasuring lag. Protection tube is wear resistance, high-temperature oxidationresistant, as well as vulcanization-resistant, liquid iron powder resistant,limestone resistant, rush-resistant, vibration-resistant etc.
