Coal stacking sensor temperature sensor pressure sensor Guolong sensor
, purpose
Coal stacking sensor is an intrinsically safe electrical equipment for mining, which is used to unload coal bunkers or other coal mine underground belt conveyors. The detection and protection requirements of the coal bunker are designed to prevent material accumulation and blockage accidents. Used for conveyor coal stacking and chute blockage protection and coal bunker high coal level detection. This product has complete functions, reliable performance, economical and practical. It is not only suitable for environments with dangerous gas and coal dust explosions in coal mines, but also for coal, metallurgy, chemical, building materials and other mines, as well as coal preparation plants, steel plants, power plants, and ports. and other harsh environmental conditions.

, Structural features and working principles
Overall structure
The sensor housing adopts an independent cavity. The upper part of the cavity is equipped with a probe rod rotating mechanism, and the sensor probe rod is installed in its side cavity. It is equipped with a travel switch assembly and a terminal assembly. There is a cable introduction device on each side of the cavity, allowing the introduction of cables with an outer diameter of ~ for wiring with external equipment.
Working Principle
The sensor is installed above the detection area and hung straight. When the material touches the sensor rod, it deflects the probe rod axis. When the probe rod deflects to a certain extent, a set of strokes inside it The switch acts and sends out a material signal.
