Explosion-proof thermocouple
|
|
| Overview |
| Industrial explosion-proof thermocouple is a temperature sensor, in the chemical industry wide application of automatic control system, through the temperature sensor, can control the temperature of the object parameters into electrical signals, passed to the display, recording and regulating device, the system Purposes of inspection, regulation and control¡£ |
| In the chemical plant, production site often accompanied by a variety of flammable, explosive and other chemical gases, steam, if ordinary thermocouple is very unsafe environment can easily cause the gas explosion. Thus, in these situations must be used for explosion-proof thermocouple temperature sensor, the company produces products of the explosive type thermocouple for temperature group d ¢ò CT6 range of explosive gases in dangerous places¡£ |
| Works: |
| If two different components of the homogeneous conductor (heat electrode) composed of a closed loop, when both ends of the temperature gradient exists when there is current through the circuit, then there exists between the two ends of thermoelectric power (as shown below) |
|
| Proof theory: |
| Using space explosion theory, the design of the junction box of sufficient strength and other parts, all will produce sparks, arc and dangerous temperatures in the junction box components are sealed, when the explosion cavity, through the extinction and the gap joints Cooling, so that the flames after the explosion and the temperature reached the cavity |
|
| Features : |
| According to international IEC standards for the design of the latest explosion of order GB3836; |
| Proof structure of a two-cavity, the replacement of temperature measurement devices is simple, safe and reliable |
Explosion-proof mark d ¢ò CT6, for ¢ò C grade below ignition temperature above T6, containing explosive gas temperature measurement occasions¡£
