In some special occasions, such as chemical plants, smelters, power plants, cement plants, etc., using ordinary thermocouples, thermal resistance is extremely vulnerable
Bad. Therefore, wear resistant thermocouples (resistance) must be used in these cases. The thermocouple (resistance) is especially suitable for a fluidized bed, a coal mill
Export, once and twice, temperature measurement in the wind coal and cement industry.
feature:
On the basis of the WR and WZ series, the insertion part of the protective cover can be made in whole or in part.
Wear-resistant, washable and corrosion resistant.
long life. It can be used for more than 6 months at high temperatures and for more than 8 months at low temperatures.
Thermocouple, the thermal resistance is a structure.
