Product description:

Explosion-proof thermocouple

Outline
Industrial explosion-proof thermocouple is a temperature sensor, the automatic control system in the chemical industry a very wide application, by the temperature sensor, can control the temperature of the object parameters into electrical signals transmitted to the display, recording and regulator of the system implementation detection, regulation and control.
In chemical plants, often accompanied by a variety of production site flammable, explosive and other chemical gases, vapors, if you use common thermocouple very unsafe, easily cause environmental gas explosion. Thus, in these situations you must use proof thermocouple as the temperature sensor, the company flameproof thermocouple products for hazardous locations with explosive gas dⅡCT6 temperature group interval.
working principle:
If two different components from a homogeneous conductor (hot electrodes) composed of a closed loop, when there is a temperature gradient at both ends, there is a current through the circuit, NA me there is between the ends of the thermoelectric power (as shown below)
Principles of explosion:
The use of space explosion principle, designed with sufficient strength to junction boxes and other components, all will produce sparks, arcs and dangerous temperature of the components are sealed in the junction box, when the cavity explosion, through the joints and gaps flameout cooling, so that after the explosion of flame and temperature not spread outside the chamber
Features:
According to the latest explosion regulations in line with international IEC standard GB3836 design;
Explosion-proof two-cavity structure, the replacement of temperature measurement devices is simple, safe and reliable

Explosion-proof mark dⅡCT6, applies to ⅡC level below the ignition temperature above T6, including temperature measurement of explosive gases occasions.
