Product Usage
The thermocouple uses compensation wires and cables to extend the cold end of the thermocouple, and is connected with the thermometer to form a temperature measurement system. It has excellent properties such as high temperature resistance, low temperature resistance, acid resistance, alkali resistance, anti-corrosion, and aging resistance. It can be immersed in oil and water for long-term use, and the normal operating temperature is -25℃~200℃.
Usage Features
1. Operating temperature: General use: -20~70℃, heat-resistant grade: -25℃~200℃.
2. Cable installation and laying temperature: not lower than 0℃.
3. Allowable bending radius: copper tape shielded winding cable shall not be less than 12 times the outer diameter of the cable, and other cables shall not be less than 6 times the outer diameter of the cable.
