WRR High temperature thermocouble explosion proof type

WRR High temperature thermocouble explosion proof type Brief Description

WRR High temperature thermocouble,explosion proof type can measure Max. temperature range from 0 to 1800℃, working temperature from 0 to 1800℃,WRR High temperature thermocouble explosion proof type used as a sensor to measure temperature, usually matched with display instruments, recording meter and electronic computer.WRR High temperature thermocouble explosion proof type can directly measure temperature from  0℃ to 1800℃ of liquid, vapor, gas medium and solid surface during various production processes. In addition,WRR High temperature thermocouble explosion proof type 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.

WRR High temperature thermocouble explosion proof type principle

WRR High temperature thermocouble explosion proof type 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 thermocouple, with a variety of installation of fixtures.
