Explosion Proof RTD Sensor
Explosion Proof Rtd Sensor can directly measure the temperature of liquid, steam and gas media and solid surface in the range of -200 to 500℃ where explosives such as hydrocarbons exist at the production site.
Working Principle Of Explosion Proof RTD Sensor:
Explosion Proof RTD Sensor uses the principle of gap and explosion-proof design to design the junction box and other components with sufficient strength, and seals all parts that may generate sparks, arcs and dangerous temperatures in the junction box cavity. When an explosion occurs in the cavity, it can be extinguished and cooled through the gap of the joint surface, so that the flame and temperature after the explosion cannot be transmitted to the outside of the cavity, this prevents explosions and allows for temperature measurement.
Features Of Explosion Proof RTD Sensor:
- Armored temperature sensing element, good anti-vibration performance;
- No need to compensate the wire, saving cost;
- High temperature measurement accuracy;
- High mechanical strength and good pressure resistance;
- Imported thin film resistor elements, reliable and stable performance;
- Explosion-proof grade: DIIBT4 DIICT6
