Way to prevent leakage in thermocouple

A lot of friends don't know how to prevent leakage in thermocouple, actually this kind of problem small make up have slightly mentioned in the previous article, small make up is the key to introduce.

a, guarantee the thermocouple in use process, will not happen and refractory brick any contact; Second, directly to the thermocouple in the cathode access to the ground, and the thermocouple with the elimination of leakage signal directly; Three, can be in the output end of the thermocouple location, directly on the set of filter device; Four, must directly from the position of thermocouple thermal contact ground will elicit and grounding; Five, in thermocouple tube with coat that is heat-resistant steel tube or silicon carbide tube, etc. , and its direct ground handling.
