GUJ30 Coal Stack Sensor

GUJ30 Coal Stack Sensor

The GUJ30 coal pile sensor is an intrinsically safe electrical equipment for mining use It is based on the requirements for the detection and protection of coal bunkers or other coal bunkers unloaded by underground belt conveyors in coal mines To prevent material accumulation Designed to cause blockage accidents. Used for conveyor coal stacking and chute blockage protection, as well as high coal level detection in coal bunkers. This product has complete functions and reliable performance. Economical and practical Not only suitable for environments with gas and coal dust explosion hazards underground in coal mines It is also applicable to mines such as dry coal, metallurgy, chemical industry, and building materials And harsh environmental conditions such as coal preparation plants, steel plants, power plants, ports, etc.
