It is applicable for the harsh environment with gas and coal dust explosion in the coal mine. Used to electrical control, monitoring and integrated protections for coal mine belt conveyor and other equipment. Equipped with smoke sensors, temperature sensors, speed sensors, coal position sensors, deviation sensors, anti-tear sensors, cable switches, sprinkler devices
and other sensor products produced by our company, can achieve protections of the low-speed skid, tear tape, coal piling, deviation, smoke, over-temperature, emergency stop and others. And to achieve over-temperature (smoke) automatic sprinkler cooling at the same time when in the temperature and smoke protection.
•With functions of centralized control, manual control, remote control and communication
•Can achieve centralized control of 8 belts, to achieve stop long the coal flow, and stop reverse coal flow
•With functions of voice alarm and fault voice alarm, fault voice alarm can both report the nature of the failure and the malfunction belt number
•Speed sensor with characteristics of real-time speed, can real-time display belt speed and set high and low-speed action value of the speed protection on the host to achieve speeding and slip protection
•Temperature sensor with characteristics of real-time temperature and speed measurement, can real-time display temperature and set action value of temperature protection on the host to achieve over-temperature protection
Coal position sensor adopts coal electrode type, whose sensitivity can be adjusted, and with high reliability
