Flameproof Thermocouple
|
|
| Detailed introduction |
???? The industrial used flame-proof thermo-element is one kind of temperature sensor, applies in the chemical industry autonomous system extremely broadly, may turn through the flame-proof thermo-element the controlled member temperature parameter the electrical signal, transmits for demonstrates the meter, the recording instrument and the accommodometer, to system execution examination, adjustment and control. |
| ??? In the chemical plant, produces the scene often to be accompanied by each kind flammable, explosive and so on chemistry gas, if uses the ordinary thermo-element to be unsafe, extremely easy to cause the environment gaseous detonation. Therefore, must use the flame-proof thermo-element in these situations to take the temperature survey measuring appliance, this company produces the flame-proof thermo-element product is suitable for EXd¢òIn the CT6 temperature category sector has in the fire damp danger place. |
| Principle of work: |
| ??? If (hot electrode) is composed the closed path by two different ingredient's isotropic conductors, when both sides existence gradient of temperature, in the return route has the electric current to pass, then between the both sides has the thermoelectric force. |
|
| Explosion-proof principle: |
| ?? Using the gap flame-proof principle, the design has enough intensity parts and so on connecting box, will possess will produce the spark, the electric arc and the dangerous temperature spare part seals in the connecting box, when in the cavity has the detonation, can through the adjoining plane gap flameout and cooling, after causing the detonation the flame and the temperature does not pass to outside the cavity. |
|
| Characteristic: |
| According to conforms to international IEC the standard newest explosion-proof regulations GB3836 design; |
| Uses two cavity type flame-proof structure, the replacement temperature element is simple, use safe reliable |
Flame-proof symbolizes EXd¢òCT6, is suitable for¢òBelow C level, above ignition temperature T6, including fire damp situation temperature survey.
