Summary:
This product is mainly used for underground coal mine containing gas and coal dust explosion danger. Coal mine spray dust removal equipment detects pedestrians or vehicles, collects mobile signals to control the spray device, and realizes automatic spray dust removal function.
Product features:
The intrinsically safe thermoluminescence infrared sensor used in mine is a kind of sensor which is composed of thermoluminescence infrared probe PIR, Fresnel lens and advanced electronic circuit and is used in automatic spray dust removal device.
Since PIR is only the most sensitive to infrared light of specific wavelength of human body and moving objects, the sensor is installed on the top of the main roadway in the underground coal mine, and it can be used together with the intrinsically safe electric ball valve of dfh-20/7 mine.
When no one is active, spray dust can be automatically restored.
