Wire and Cable
Compensation wire and cable for thermocouple

The function of the thermocouple with the compensation wire is to extend the cold end of the hot electrode, that is, the mobile thermocouple, and connect it with the display instrument to form a temperature measurement system. This product adopts GB / T 4989-94 "Compensation wire for thermocouple" national standard (equivalent to IEC584-3 "Thermocouple part III-Compensation wire" international standard). And adopt the new continuous continuous extrusion process, so that the product has excellent acid resistance, alkali resistance, wear resistance and non-combustible properties, can be immersed in oil and water for long-term use. The use temperature is -60-205-260 ° C, which belongs to the advanced international level. The products are mainly used in various temperature measuring devices and have been widely used in petroleum, chemical, metallurgy, power and other departments.
Model indication

Main Specifications:
Compensation wire model is divided into SC, KC, KX, EX, JX, TX, NC according to the product type
Among them: a) the first letter of the model corresponds to the graduation number of the thermocouple;
b) The letter "X" indicates an extended compensation lead (type);
c) The letter "C" indicates a compensation type compensation lead (type).
Note: SC type compensation wire can be used with R type indexing thermocouple
