Thermocouple cable
Extension cable is a special wire used in the temperature measurement method of a thermocouple cable used by extending a wire made of the same material as a thermocouple to the measuring instrument terminal. In this case, since the thermocouple material is expensive, it requires a lot of cost to use it for a long time. Therefore, thermocouple cable made of relatively inexpensive materials with little error is needed, which is compensating cable.
In modern times, it is absolutely necessary to ensure economic feasibility with high efficiency by measuring and managing accurate temperatures, and to make the quality of products uniform and high-quality. In particular, it is widely used in all industrial sites that require heat management, from shipbuilding and automobiles to small boilers, in addition to various power plant facilities, process management of petrochemical plants, and steel smelters.
