Industrial explosion-proof product characteristics and the applications of the thermocouple

Industrial explosion-proof thermocouple thermocouple is a kind of sensor, application is very broad, in the chemical industry automatic control system, temperature control object parameters of the temperature sensor can be converted into electrical signals, and pass to monitor, recorder and controller, system test execution.

explosion-proof thermocouple

to adjust and control. In chemical plant, if you use a common thermocouple, very unsafe, caused by the extreme conditions of gas explosion, the production process is often accompanied by various kinds of flammable and explosive chemicals, steam. In these cases, therefore, you must use explosion-proof thermocouple temperature sensor.

the application of explosion-proof thermocouple is usually display instruments, recording instruments, form a complete set to use a computer. Direct measurement of hydrocarbons and other explosive liquid, within the scope of 0 ℃ ~ 1300 steam and gas and solid surface temperature.

:

varieties form of explosion-proof, explosion-proof performance is good; Compression spring type thermal components, shock resistant performance is good; Measuring range is large; High mechanical strength, good compression performance; Working principle of the explosion-proof thermocouple are using clearance through the principle of design has enough strength of the junction box, parts, can produce sparks, sealing parts and electrical parts and dangerous temperature within the junction box, box when the explosion. In chemical plant, if use normal thermocouple, very unsafe, caused by the extreme conditions of gas explosion, often accompanied by various chemical gas production process, such as inflammable and explosive gas. In these cases, therefore, must use explosion-proof thermocouple as the temperature measuring instrument, three cheong instrument production explosion-proof thermocouple products is suitable for the dangerous sites with explosive gas level of EXd II CT6 temperature range.
