The function of thermocouple compensation wire is to extend the hot electrode that is to move the cold end of the thermocouple, and the display instrument is connected to form a temperature measuring system. The insulating layer and protective layer are made of imported high quality fluorine plastic, and the whole continuous extrusion process is adopted, so that the product has excellent acid resistance, alkali resistance, wear resistance and non-flammable properties, and can be immersed in oil and water for a long time to use. Using temperature - 60-205-260℃, belongs to the contemporary international advanced level. Thermocouple compensation wire, compensation cable is mainly used in various temperature measuring devices, has been widely used in petroleum, chemical, metallurgy, electric power and other departments. Features: 1. High precision and good stability; 2. High sensitivity and good linearity; 3. Short response time and good compatibility; 4. Compact structure, easy installation, good waterproof performance
