GKT5L Device start stop sensorDetailed product description：

The GKT5L equipment on/off sensor mainly monitors the on/off status of underground mechanical and electrical equipment in coal mines (such as coal mining machines, transport machines, elevators, crushers, local fans, pump stations, fans, etc.), and converts the detected equipment on/off signals into various standard signals, which are transmitted to the coal mine monitoring and control system. It can achieve centralized and continuous automatic monitoring of the on/off status of the entire frame electrical equipment from the ground.

The GKT5L equipment on/off sensor is a practical and reliable automation equipment that ensures safe production in mines and monitors the production status in real time. It can also be used as a basis for calculating the operation quality, duration, and utilization rate of various mechanical and electrical equipment. This sensor is of mining intrinsic safety type and adopts a new optimized design. It has the characteristics of novel structure, easy installation and use, low power consumption, strong adaptability, stable and reliable performance, and maintenance free. The output form is suitable for supporting various domestic detection systems and is suitable for monitoring various AC driven electromechanical equipment with a power supply current greater than 5A.

Main parameters of GKT5L equipment start stop sensor
Action value: 5A, allowable error of action value: not exceeding ± 1A
Rated working voltage: 12V.DC;  
Working current: ≤ 30mA
Type of power cable for the tested equipment: mining power cable, diameter: (Φ 10~Φ 30) mm;  
Response time (s): ≤ 1;

Functional Features
The sensor adopts an inherently safe structure and has no direct electrical connection with the device under test. When in use, simply clamp the sensor directly onto the outer sheath of the power cable of the device under test, making installation, use, and adjustment very convenient;  
The shell is made of high-strength ABS engineering plastic, which has the advantages of beauty, good protection, and not easily damaged. It can ensure the long-term reliable operation of the sensor when used underground in coal mines;  
There is an observation window on the shell to observe the green and red light-emitting tubes, which respectively indicate the on and off status of the equipment when lit up. There is a potentiometer on the circuit board to adjust the sensitivity of the detection signal;  
When the current of adjacent cables is not less than 3 times the corresponding action value current, the sensor will not malfunction;
