What are the requirements for the thermocouple in the structure

Commonly used thermocouple can be divided into two categories, the standard thermocouples and standard thermocouples, one of the standard thermocouple is mainly refers to, according to the relevant provisions of the relationship between temperature and thermoelectric potential, can be there is a certain error, and have the same standard indexing table thermocouple products, and its own has the mutual matching display instrument; Rather than a standard thermocouple used in the whole range, and less quantity than standard thermocouple, although also have the same indexing table, but is only suitable for use on special occasions.

in order to ensure the stable and reliable operation of thermocouple can for its in structure mainly has the following requirements: a hot thermocouple, mix into the two electrodes, on the whole welding must be strong enough; Second, the two heat between the electrodes, must have good insulation, avoid the phenomenon of short circuit; Three compensation wire, thermocouple, and the free end, between the connection not only reliable and more convenient; Four, and protect casing must be ensure the hot electrode, and harmful medium can be fully isolated.
