WRE-54 WRE2-54 WRF-54 WRF2-54 Explosion proof thermocouple

Overview of WRE-54 WRE2-54 WRF-54 WRF2-54 Explosion proof thermocouple

Explosion proof thermocouple industrial explosion-proof thermocouple is a kind of temperature sensor, which is widely used in the automatic control system of chemical industry. Through the temperature sensor, the temperature parameters of the control object can be transformed into electrical signals, which can be transmitted to the display, recording and regulator to detect and adjust the system

Regulation and control. In chemical plants, the production site is often accompanied by various flammable, explosive and other chemical gases and vapors. If ordinary thermocouples are used, it is very unsafe and it is very easy to cause ambient gas explosion. Therefore, flameproof thermocouples must be used as temperature sensors in these occasions.

Explosion proof thermocouple is usually used together with display instrument, recording instrument, electronic computer, etc. Directly measure the surface temperature of liquid, steam, gas medium and solid within the range of 0 ℃ ~ 1300 ℃ where there are explosives such as hydrocarbons on the production site. Features: various explosion-proof forms, good explosion-proof performance; Pressure spring type temperature sensing element with good anti vibration performance; Large measurement range; High mechanical strength and good pressure resistance; Working principle explosion proof thermocouple uses the gap explosion-proof principle to design junction boxes and other components with sufficient strength to seal all parts that will produce sparks, electric isolation and dangerous temperature in the junction box. When explosion occurs in the box.

Working principle of WRE-54 WRE2-54 WRF-54 WRF2-54 Explosion proof thermocouple

Explosion-proof thermocouples are designed with sufficient strength of junction boxes and other components by using the gap explosion-proof principle, and all parts that will generate sparks, arcs and dangerous temperatures are sealed in the junction box cavity. When an explosion occurs in the cavity, it can be The flame and temperature after the explosion cannot be transmitted to the outside of the cavity by extinguishing and cooling through the gap of the joint surface, so as to prevent explosion.
