explosion proof temperature sensor is a kind of temperature sensor, which is widely used in chemical industry automatic control system. Through the temperature sensor, the temperature parameter of the controlled object can be turned into an electrical signal, which can be transmitted to the display, record and regulator to perform detection and control of the system. Regulation and control. In chemical plants, the production site is often accompanied by various flammable and explosive chemical gases and steam. It is very unsafe to use ordinary thermocouples, and it is very easy to cause environmental gas explosions.
explosion proof temperature sensor Explosion-proof classification form
Explosion-proof grade Explosion proof grade of explosion-proof thermocouple
according to maximum test safety clearance of mixture of explosive gas is divided into A, B, C.
explosion proof temperature sensor Temperature group
Temperature groups of explosion-proof thermocouple is divided into T1~T6 according to maximum surface temperature of the exposed part.
The difference between explosion proof temperature sensor and ordinary thermocouple
In industrial measurement, there are very powerful advantages. What are the specific advantages? What is the difference with ordinary thermocouples? Let me talk about it.
Explosion-proof thermocouple compression spring type temperature sensing element, good vibration resistance; large measurement range; high mechanical strength, good pressure resistance; working principle Explosion-proof thermocouple uses the principle of gap explosion-proof, designing a junction box and other components with sufficient strength, All parts that will generate sparks, electric isolation and dangerous temperature are sealed in the junction box, when an explosion occurs in the box. Explosion-proof thermocouple Industrial explosion-proof thermocouple is a kind of temperature sensor, which is widely used in chemical industry automatic control system. Through the temperature sensor, the temperature parameter of the controlled object can be turned into an electrical signal, which is transmitted to the display, record and regulator. Perform testing on the system. Explosion-proof thermocouples directly measure the surface temperature of liquid, vapor and gaseous media and solids in the range of 0℃～1300℃ where there are explosives such as hydrocarbons at the production site. Features: Various explosion-proof forms, good explosion-proof performance.
explosion proof temperature sensor use the gap explosion-proof principle, design the junction box and other components with sufficient strength, and seal all the parts that generate sparks, arcs and dangerous temperatures in the junction box cavity. When an explosion occurs in the cavity, it can Extinguish and cooling through the gap of the joint surface, so that the flame and temperature after the explosion can not be transmitted to the outside of the cavity, so as to achieve explosion-proof.more explosion proof temperature sensor.
