The difference between explosion-proof thermocouple and conventional thermocouple
Explosion-proof thermocouple is a special kind of thermocouple. The difference between explosion-proof thermocouple and conventional thermocouple? Compared with ordinary thermocouples, explosion-proof thermocouples have the following two characteristics:
1. The compression spring type temperature sensing element of the explosion-proof thermocouple has good anti-vibration performance; large measuring range; high mechanical strength and good pressure resistance. Explosion-proof thermocouples use the principle of gap explosion-proof, design a junction box and other components with sufficient strength, and seal all parts that generate sparks, electric isolation and dangerous temperature in the junction box, when an explosion occurs in the box.
2. Explosion-proof thermocouples are suitable for chemical plants. The production site is often accompanied by various flammable and explosive chemical gases and vapors. It is very unsafe to use ordinary thermocouples and can easily cause environmental gas explosions.
Therefore, flameproof thermocouples must be used as temperature sensors in these occasions. Explosion-proof thermocouple applications are usually used in conjunction with display instruments, recording instruments, electronic computers, etc., to directly measure the surface temperature of liquid, vapor and gaseous media and solids in the range of 0°C to 1300°C where hydrocarbons and other explosives are present at the production site.Detail about Explosion proof thermocouple thermometer
