WRKN Wear resistant thermocoupleDetailed product description：

WRKN wear-resistant thermocouple

1. Overview

Due to the use of different high-strength wear-resistant protective tubes and surface modification measures for different temperature ranges and tested media, a composite tube type solid structure is formed. This series of products is suitable for temperature measurement of flowing powders and materials such as petrochemicals, coal transportation systems, fluidized bed boilers, cement clinker, and refractory materials with severe wear of protective tubes. Further improve the service life of thermocouples. Its performance is superior to current wear-resistant thermocouples and has won high praise from users.
