WRM-54 WRM2-54 WRN-54 WRN2-54 Explosion proof thermocouple

Overview of WRM-54 WRM2-54 WRN-54 WRN2-54 Explosion proof thermocouple

WRM-54 WRM2-54 WRN-54 WRN2-54 Explosion proof thermocouple is a kind of temperature sensor, which is single or 2double support, adjustable pipe joint type, explosion proof junction box form. it can widely used in chemical industry automatic control system. Through the temperature sensor, the temperature parameters of the controlled object can be changed into electrical signals, which can be transmitted to the display, record and regulator, so as to detect, adjust and control the system. In chemical plants, the production site is often accompanied by a variety of flammable, explosive and other chemical gases, steam, if the use of ordinary thermocouple is very unsafe, easy to cause environmental gas explosion.

Regulation and control. In chemical plants, the production site is often accompanied by a variety of flammable, explosive and other chemical gases, steam, if the use of ordinary thermocouple is very unsafe, easy to cause environmental gas explosion. Therefore, flameproof thermocouples must be used as temperature sensors in these situations.
Explosion proof thermocouple applications are usually used in conjunction with display meters, recording meters, electronic computers, etc. Directly measure the surface temperature of liquid, steam, gas and solid in the range of 0 ° C to 1300 ° C where explosives such as hydrocarbons are present in the production site. Features: various explosion-proof forms, good explosion-proof performance; Pressure spring type temperature sensing element, good vibration resistance; Large measurement range; High mechanical strength, good pressure resistance; Working principle Explosion-proof thermocouple is the use of the gap explosion-proof principle, design with sufficient strength of junction box and other parts, will produce sparks, electric arc and dangerous temperature parts are sealed in the junction box, when the box explosion.

Working principle of WRM-54 WRM2-54 WRN-54 WRN2-54 Explosion proof thermocouple

If a closed loop is composed of two homogeneous conductors (thermal electrodes) of different components, when there is a temperature gradient at both ends, the loop There's a current going through, and there's a thermoelectric potential between the two ends Explosion-proof original use of gap explosion-proof principle, design with sufficient strength of junction box and other components, will all spark, arc and dangerous temperature of the zero parts are sealed in the junction box, when the explosion occurs in the cavity, through the joint surface gap extinguisher and cooling, so that the flame and temperature after the explosion does not spread to the outside of the cavity.
