Overview
The GKT5L equipment on/off sensor is mainly used to monitor the on/off status of underground electromechanical equipment in coal mines, and convert the detected equipment on/off signals into various standard signals for transmission to the coal mine monitoring system. It can achieve centralized continuous automatic monitoring of the on/off status of electrical equipment in the entire mine from the ground.
