Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 Brief Description

Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 industrial assembly-type thermocouple with double output signal,movable flange square connction,splash proof type,Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 is used as a sensor to measure temperature, Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 usually matched with display instruments, recording meter and electronic computer.Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 can directly measure temperature from 0℃ to 800℃ of liquid, vapor, gas medium and solid surface during various production processes. In addition, Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 has the advantages of simple assembly, convenient replacement, pressure spring type temperature sensing element, good anti-vibration, wide measuring range, high mechanical strength, good pressure durability.

 

Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 Working principle

Thermocouple WRE2-530 WRE2-531 WRE2-532 WRE2-533 working principle: two conductors with different components are welded at both ends to form a loop, measuring temperature directly side is called measurement side, terminal side is called reference side. When the temperature between measurement side and reference side has a difference, it will generate heat in the loop current, then connected to the display instrument, And the instrument indicates the corresponding temperature value of the thermal electromotive force generated by the thermocouple. Thermocouple thermoelectric EMF will grow with the measurement temperature’s growth, The size of the thermal electromotive force is related to the temperature of both ends. It has nothing to do with the length, diameter of the thermode.

Junction box, protective tube, insulated casing, termals and thermal electodes form a basic structure of assembly-type WRE2-530 WRE2-531 WRE2-532 WRE2-533 thermocouple, with a variety of installation of fixtures.
