N40H All the snesors are used for the mine with combustible gas (methane) and coal dust to protect and control the Belt Conveyor, it can also be used for the centrlized (along with) scraper conveyor control and protection. The above sensor could realize the protection of high coal position, low coal position in the hopper, the coal postion under the belt conveyor head, sliding with low speed, belt break up, over speed, deviation and smoke to enhance the safety, advantage, realiablity, convenience and energy saving to the belt conevyor.
