YK-WRNL/M

Wear-Resistant Thermocouple / RTD

The YK-WRNL/M wear-resistant thermocouple (RTD) is a newly developed temperature sensor featuring advanced wear-resistant protection tubes made of plasma spray coating, high-chromium cast iron, and K-alloy materials. This design significantly improves abrasion resistance, extends service life, and broadens the temperature measurement range. It is suitable for applications with severe probe wear, such as circulating fluidized bed boilers in power plants, ball mills, coal mills, as well as cement and metallurgical industries.
