Micro thermocouple

The principle of micro thermal resistance

The working principle of a micro thermocouple is that two conductors with different compositions are welded at both ends to form a circuit. The temperature measuring end is called the working end, and the wiring terminal end is called the cold end, also known as the reference end. When there is a temperature difference between the working end and the reference end, a thermal current will be generated in the circuit. When connected to a display instrument, the instrument will indicate the corresponding temperature value of the thermoelectric potential generated by the thermocouple. The thermoelectric potential of a micro armored thermocouple will increase with the temperature at the measuring end. The magnitude of the thermoelectric potential is only related to the material of the thermocouple conductor and the temperature difference at both ends, and is independent of the length and diameter of the thermoelectric electrode.
