Wear resistant thermocouple, its working part can withstand the impact of high-speed particles, is not easily worn, and has a long service life. The wear-resistant thermocouple with a cut-off valve can cut off the thermoelectric electrode by closing the cut-off valve when the thermocouple is damaged, which enhances the safety of thermocouple use and is easy to replace.
