Explosion proof thermocouple with fixed screw

Overview of Explosion proof thermocouple with fixed screw

Explosion proof thermocouple with fixed screw is a kind of temperature sensor, which is widely used in chemical industry automatic control system. Through the temperature sensor, the temperature parameters of the controlled object can be changed into electrical signals, which can be transmitted to the display, record and regulator, so as to detect, adjust and control the system. In chemical plants, the production site is often accompanied by a variety of flammable, explosive and other chemical gases, steam, if the use of ordinary thermocouple is very unsafe, easy to cause environmental gas explosion.

The working principle of Explosion proof thermocouple with fixed screw
If by two kinds of different ingredients of homogeneous electrode (heat) closed conductor loop, when the temperature gradient is at both ends, the current through the loop, so both existed between thermoelectric potential explosion proof using the clearance flame-proof principle, design has enough strength of the junction box, and other components, all can produce spark, arc and dangerous temperature zero parts are sealed in the junction box, When there is an explosion in the cavity, the flame can be extinguished and cooled through the joint surface gap, so that the flame and temperature after the explosion is not transmitted to the outside of the cavity.

Product features of Explosion proof thermocouple with fixed screw

Flameproof mark D ⅱ CT6, suitable for ⅱ C level below, ignition temperature above T6, containing explosive gas temperature measurement.

Explosion-proof thermocouple industry flameproof thermocouple is a kind of temperature sensor, which is widely used in chemical industry automatic control system. Through the temperature sensor, the temperature parameters of the control object can be changed into electrical signals, which can be transmitted to display, record and regulator, so as to detect, adjust and control the system. In chemical plants, the production site is often accompanied by a variety of flammable, explosive and other chemical gases, steam, if the use of ordinary thermocouple is very unsafe, easy to cause environmental gas explosion. Therefore, flameproof thermocouples must be used as temperature sensors in these situations.

Application of Explosion proof thermocouple with fixed screw
features of Explosion proof thermocouple with fixed screw are usually used in conjunction with display meters, recording meters, electronic computers, etc. Directly measure the surface temperature of liquid, steam, gas and solid in the range of 0 ° C to 1300 ° C where explosives such as hydrocarbons are present in the production site. Features: various explosion-proof forms, good explosion-proof performance; Pressure spring type temperature sensing element, good vibration resistance; Large measurement range; High mechanical strength, good pressure resistance; Working principle Explosion-proof thermocouple is the use of the gap explosion-proof principle, design with sufficient strength of junction box and other parts, will produce sparks, electric arc and dangerous temperature parts are sealed in the junction box, when the box explosion.
