Talking about the working principle and technical parameters of explosion-proof thermocouple

by:JVTIA     2022-02-28
Explosion-proof thermocouple industrial explosion-proof thermocouple is a kind of temperature sensor, which is widely used in the chemical industry automatic control system. Through the temperature sensor, the temperature parameters of the control object can be converted into electrical signals and transmitted to the display, recording and conditioning instruments. Detect, condition and control the system. In chemical plants, the production site is often accompanied by various flammable, explosive and other chemical gases and vapors. If ordinary thermocouples are used, it is very unsafe, and it is easy to cause environmental gas explosions. Therefore, explosion-proof thermocouples must be used as temperature sensors in these places. Explosion-proof thermocouples are usually used in conjunction with display instruments, recording instruments, and electronic computers. Directly measure the temperature of liquid, steam and gas medium and solid surface in the range of 0℃~1300℃ where there are explosives such as hydrocarbons at the production site. Features: a variety of explosion-proof methods, good explosion-proof performance; compression spring temperature sensing element, good vibration resistance; large measurement range. High mechanical strength and good pressure resistance; working principle Explosion-proof thermocouples are based on the principle of gap explosion-proof, design junction boxes and other components with sufficient strength, and seal all parts that will generate sparks, electrical isolation and risk temperature in the junction box. inside, when an explosion occurs inside the box. It is suitable for temperature measurement and control in narrow and bending places. It is an indispensable temperature measuring device in chemical, chemical fiber, pharmaceutical and other industries. Explosion proof thermocouple conditioning and control.
