Armored thermocouple structure principle and introduction

The armored thermocouple can generally measure the surface or internal temperature of gases, liquids and vapors and solids in the range of 0 ~ 1300℃.Armored thermocouple can be used with digital instrument, recording and regulating instrument, PLC, data collector or computer, as a new generation of temperature sensor, it can be widely used in metallurgy, petroleum, chemical, electric power, light industry, textile, food, national defense and scientific research departments.
The thermoelectric emf of the armored thermocouple will increase with the increase of the temperature at the measuring end.

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



Structure principle of armored thermocouple application of armored thermocouple
Is by the conductor, high insulation magnesium oxide, coat 1Cr18Ni9Ti stainless steel protection tube, after many times one pull system.Armored thermocouple products are mainly composed of terminal box, terminal and armored thermocouple basic structure, and equipped with a variety of installation fixed devices.

Armored thermocouple insulation type and shell type.
Armored thermocouple has many advantages such as bending, high pressure resistance, fast thermal response time and durability, etc. It is the same as industrial use, as a temperature sensor, usually used with digital display, recording instrument and electronic regulator, at the same time, can also be used as a temperature sensor.It can directly measure the temperature of liquid, steam and its gaseous medium and solid surface in various production processes from 0℃ to 800℃.In comparison, the armored thermocouple has the advantages of bendability, high pressure resistance, short thermal response time and durability.
