Overview of WRP-120 WRP2-120 WRP-121 WRP2-121 Type S thermocouple

WRP-120 WRP2-120 WRP-121 WRP2-121 Type S thermocouple uses precious metal high-purity platinum as the negative electrode and platinum rhodium alloy as the positive electrode. It is used for powder metallurgy, sintering bright furnace, vacuum furnace, smelting furnace and firing of various refractory materials, ceramics and porcelain. The outer tube is made of corundum and the measuring temperature is 0-1800 ℃.

Working principle of WRP-120 WRP2-120 WRP-121 WRP2-121 Type S thermocouple

The working principle of thermocouple is that the two ends of two conductors with different components are welded to form a loop. The direct temperature measuring end is called the measuring end, and the terminal end is called the reference end. When there is a temperature difference between the measuring end and the reference end, thermal current will be generated in the circuit. When the display instrument is connected, the instrument will indicate the corresponding temperature value of the thermoelectric electromotive force generated by the thermocouple.

The thermoelectric electromotive force of the thermocouple will increase with the increase of the temperature at the measuring end. The thermoelectric electromotive force is only related to the material of the thermocouple conductor and the temperature difference at both ends, and has nothing to do with the length and diameter of the Thermoelectrode.

The assembled thermocouple is mainly composed of a junction box, a protective tube, an insulating sleeve, a terminal block and a Thermoelectrode, and is equipped with various installation and fixing devices.
