Distinguish explosion proof thermocouple and flameproof thermocouple

       Industrial use flameproof explosion-proof thermocouple thermocouple is a temperature sensor in the chemical industry in the automatic control system is widely used, the temperature sensor can be temperature control object parameters into electrical signals transmitted to display, record and control apparatus, the detection system implementation

Explosion-proof thermocouple

      Regulation and control. In the chemical plant, the production site is often accompanied by a variety of flammable, explosive and other chemical gases, steam, and if the use of ordinary thermocouple is very unsafe, it is easy to cause environmental gas explosion. Therefore, flameproof thermocouples must be used as temperature sensors on these occasions.

Flameproof thermocouple applications are usually used in conjunction with display instruments, recording instruments, and electronic computers. The liquid, steam and gas medium and the temperature of the solid surface are measured directly in the presence of explosives such as hydrocarbons at the production site 0 ~ 1300 degrees centigrade.


       Various forms of explosion-proof, explosion-proof performance; the pressure spring type temperature sensing element, good vibration resistance; measurement range; high mechanical strength, good pressure resistance; working principle is the use of explosion-proof thermocouple gap explosion-proof junction box component design principle, with sufficient strength, will all produce a spark, arc and danger the temperature of the parts are sealed in the junction box, when the explosion occurred inside the box.
