Analysis of the working principle of armor WRNK-191

Armored WRNK-191 has the characteristics of bending and fast thermal response time. Like industrial assembled thermocouples, it is used as a temperature sensor and is usually used in conjunction with display instruments, recording instruments, and electronic regulators. At the same time, it can also be used as a temperature sensing element for assembled thermocouples. It can directly measure the temperature of liquid, steam, gas media, and solid surfaces from 0 ℃ to 900 ℃ in various production processes.

Working principle of armor WRNK-191:

1. It is formed by welding two conductors with different compositions at both ends to form a circuit. The direct temperature measuring end is called the measuring end, and the connecting end is called the reference end. When there is a temperature difference between the measuring 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.

2. The thermoelectric potential of the armored thermocouple will increase with the temperature rise at the measuring end. The magnitude of the thermoelectric potential is only related to the material of the armored thermocouple conductor and the temperature difference between the two ends, and is independent of the length and diameter of the thermoelectric electrode.
