Product overview
The TAR wear resistant thermocouple (thermal resistance) is a wear-resisting protective tube made from high-chromium iron and K alloy by the plasma spraying technology which greatly improves the abradability, prolongs the service life, expands the temperature measurement range and applies to the occasions where the protective tube of the temperature sensor is seriously worn (such as power plant circulating vulcanized bed boiler, coal mill, cement plant and smelting plant).
