• KGT9-A mining electromechanical equipment start-stop sensor, KGT9-E mining electromechanical equipment start-stop sensor is mainly used for monitoring the start-stop status of underground coal mine electromechanical equipment (such as coal miner, conveyor, elevator, crusher, bureau fan, pumping station, blower, etc.), and convert the detected start-stop signals into all kinds of standard signals to be transmitted to the monitoring system of the mine (or other carrier equipment transmitting information to the ground, etc.), which can realize the centralized continuous automatic monitoring of the whole mine electrical equipment from the ground. The sensor can realize the centralized and continuous automatic monitoring of the opening and closing status of the electrical equipment of the whole mine from the ground. The sensor is to ensure safe production in the mine, real-time monitoring of mine production conditions, practical and reliable automation equipment, can also be used as a basis for statistics on the operation of various mechanical and electrical equipment, running time and equipment utilization.
