Overview:

WREK-1313 multi point armored thermocouple has many advantages of suchas flexible, high pressure- resistant, fast thermal response time anddurability and so on. It can be used as a temperature sensor which is the sameto the industrial fabricated thermocouple. It is usually used with displayinstrument, record instrument and electronic regulator, at the same time, alsocan be temperature components for the fabricated thermocouple. In the processof production it can directly measure all liquid, steam and gas and solidssurface temperature from 0℃~800 ℃, which complies with IEC standard.

Working Principle:

The principle of WREK-1313 multipoint armored thermocouple is that tow conductors with different components arewelded at both ends to form a loop, the direct temperature side is called measurementside, the terminal side is called reference junction. When measuring side andreference side have a different temperature, it will generate heat in the loop,and then connected to the display instrument, and then the instrument indicatesthe corresponding temperature value of the thermal electromotive forcegenerated by the thermocouple.

The force of WREK-1313 multi point armoredthermocouple will increase along with the temperature increasing of measurementside. The size of thermocouple force is only related to the conductor materialas well as the temperature differential of both sides, which has no relationshipwith the length and diameter of the thermo.

The multi point armored thermocouple ismade of the conductor, insulation, magnesia and 304SS stainless steelprotection tubes after drawing many times. Armored thermocouple products mainlyconsists of wiring box, terminals and element of armored thermocouple, andmatched with various of installation fixed device component.
