KB/KR/KS/KW Rapid Temperature Measurement Thermocouple High Accuracy Thermocouple


【 Structural Analysis 】
The structure of a Fast Thermocouple
is mainly composed of a temperature thermocouple head and a large paper tube. The thermocouple head mainly consists of positive and negative thermocouple wires welded to the compensation wire for fast thermocouple, and the compensation wire is embedded in the bracket. The bracket is covered with a small paper tube, and the thermocouple wire is supported and protected by quartz. Equipped with an anti slag cap on the outside, all components are concentrated in the mud head and glued together with a fire-resistant filling agent, making it non detachable and therefore disposable.


【 Working Principle 】
Based on the thermoelectric effect of metals, the temperature difference generated at both ends of Thermocouples is used to measure the temperature of molten steel and high melting metals. Two different components of conductors are welded at both ends to form a circuit. The direct measurement end is called the working end (hot end), and the wiring terminal end is called the cold end. When there is a temperature difference between the hot end and the cold end, a thermal current will be generated in the circuit. When connected to a display instrument, the corresponding temperature value of the generated thermoelectric electromotive force will be indicated on the instrument, and the electromotive force will increase with the increase of temperature.
