Open GKT5 device to stop the sensor, and off the price of the sensor, open the stop sensor manufacturers 
 Scope and Features 
 Open stop sensor GKT5 equipment is mainly used for monitoring underground coal mine electrical and mechanical equipment (eg, Shearer, transport aircraft, elevator, crusher, local fan, pumping stations, fans, etc.) of the OFF state, and detection equipment to open the stop signal converted into a variety of standard signal transmission to the mine monitoring system (or other information transmitted to the ground carrier equipment, etc.), can be achieved by the face of all mine electrical equipment open to stop the state focus on continuous automatic monitoring. 
 The sensor is to ensure that the mine safety in production, real-time monitoring of mine production status of practical and reliable automation equipment, but also as the statistics of various electrical and mechanical equipment operation good or bad, running the length of time and equipment utilization basis. 
 The sensor is mine intrinsically safe, using the new optimized design. Has a novel structure, easy installation, low power consumption, adaptable, reliable performance, maintenance-free characteristics. The output format has formed a series, suitable for supporting a variety of monitoring systems at home and abroad, applies to electrical and mechanical equipment monitoring the supply current is greater than 5A AC drive. 
 In addition to used in conjunction with the Company's the KJ205 type of coal mine safety production monitoring system and other mine monitoring system compatible.
