ZP-12S Voice controlled sensor for automatic water spraying and dust reduction device in miningDetailed product description：

The sound controlled sensor used in the ZP-12S mining automatic sprinkler dust reduction device has the characteristics of novel structure, reliable performance, and convenient use. This sensor is suitable for working environments such as mining faces, transportation tunnels, underground car yards, belt conveyors, and coal storage yards in mines with explosive gas (methane) and coal dust hazards. It is connected to the ZP127-Z mining automatic sprinkler dust reduction device host (hereinafter referred to as the host) to form an automatic sprinkler dust reduction device. It can not only reduce dust and purify the air, but also absorb certain harmful gases, reduce gas concentration and environmental concentration. It is an important facility for improving and controlling dust working environments and effectively preventing dust hazards.
