What are the advantages of armored thermocouples relative to other types of thermocouples?
The type of thermocouple is also very much, with platinum and rhodium thermocouple, wear-resistant thermocouple, corrosion thermocouple, assembly thermocouple, K-type thermocouple, armored thermocouple, and so on. Which is the use of armored thermocouple is very wide, in many industries have applications, then the advantages of armored thermocouple which we all know? The following by the Xin Rui instrument for everyone to introduce it in detail:
The characteristics of armored thermocouple
Armored thermocouples have the advantages of being able to bend, withstand high pressure, fast response times and ruggedness. Armored thermocouples, like assembled thermocouples, are used as sensors for measuring temperature, usually with armored thermocouples and display instruments, Electronic regulator supporting the use of the same time, armored thermocouple can also be used as assembly thermocouple temperature sensor. Armored thermocouples can directly measure the temperature of liquids, vapors and gaseous media and solid surfaces from 0 ° C to 1100 ° C in various production processes.
The principle of armored thermocouple
Armored thermocouple works, two different components of the conductor at both ends of the welding, the formation of the loop, the direct temperature measurement called the work side, the terminal end called cold end, also known as the reference side. When the working side and the reference side of the existence of temperature difference, it will generate heat in the loop, connected to the display instrument, the instrument will indicate the thermocouple generated by the corresponding thermoelectromotive force value.
The thermoelectromotive force of the armored thermocouple will increase with the increase of the temperature at the measuring end. The size of the thermoelectromotive force is only related to the thermocouple conductor material and the temperature difference between the two ends, regardless of the length and diameter of the hot electrode.
The Structural Principle of Armored Thermocouple
Armored thermocouple is made of conductor, high insulation magnesium oxide, jacket 1Cr18Ni9Ti stainless steel protection tube, after repeated drawn from one. Armored thermocouple products mainly by the junction box, terminal blocks and armored thermocouple composed of the basic structure, and with a variety of installation of fixed devices.
