1. Explosion-proof thermal resistance is usually used together with display instruments, recording instruments, etc. Directly measure the temperature of liquid, steam and gas medium and solid surface in the range of 0 ~ 500 ℃ where there are explosions such as hydrocarbons on the production site.
Explosion-proof thermal resistance features: Compression spring-type temperature sensing element, good anti-vibration performance; high measurement accuracy; high mechanical strength, good pressure resistance performance; imported film resistance element, reliable and stable performance;
Working principle of explosion-proof thermal resistance:
Explosion-proof thermal resistance uses the principle of gap flameproof to design the junction box and other components with sufficient strength. All components that will produce sparks, arcs and dangerous temperatures are sealed in the junction box cavity. The surface gap is extinguished and cooled, so that the flame and temperature after the explosion cannot be transmitted to the outside of the cavity for temperature measurement.
Industrial explosion-proof thermocouple is a kind of temperature sensor. It is widely used in the chemical industry automatic control system. Through the temperature sensor, the temperature parameter of the control object can be converted into an electric signal, which is transmitted to the display, record and adjuster to implement the system. Detection, regulation and control. In chemical plants, the production site is often accompanied by various flammable and explosive chemical gases and steam. If ordinary thermocouples are used, it is very unsafe and can easily cause environmental gas explosion. Therefore, explosion-proof thermocouples must be used as temperature sensors in these occasions. The explosion-proof thermocouple products produced by our company are suitable for use in places with explosive gas dangers in the dⅡCT6 temperature group interval.
