GEJ20/35 (A) intrinsically safe deviation sensor for mining use

This product is an intrinsically safe electrical equipment for mining, suitable for workplaces such as underground coal mines, open-pit coal mines, and coal preparation plants. It is used for detecting belt deviation in belt conveyors.

Main parameters of GEJ20/35 (A) intrinsically safe deviation sensor for mining use

Action angle: Level 1: 20 °± 2 °; Level 2: 35 °± 2 °; Reset angle: Level 1:<16 °; Level 2:<30 °.  
The maximum angle of rotation for the probe is ≥ 70 °.  
Action direction: 360 °, action level: dual level, action force: (20-100) N.  
Action performance: The sensor is subjected to action force, and when the probe rotates to the action angle, it should immediately move and the normally open contact should close. When the action force is removed and the probe rod automatically returns to its original position, it immediately recovers after the reset angle, and the normally open contact is disconnected.

Functional characteristics of GEJ20/35 (A) intrinsically safe deviation sensor for mining

Small size, light weight, good sealing performance, and easy maintenance; After the contact action, there is still a large buffer angle for the rotation of the probe rod, making it less likely to be damaged.  
When the belt of the belt conveyor deviates, the belt forces the shaft roller to deviate. When the swing angle of the shaft roller of the deviation sensor is ≥ 20 º, the first level micro switch will act and issue a warning signal. When the swing angle of the shaft roller of the deviation sensor is ≥ 35 º, the second level micro switch will act and issue a stop signal, cutting off the control circuit of the belt conveyor and stopping the machine or sending a deviation fault signal to the monitoring station. After the fault is eliminated, the shaft roller of the deviation sensor returns to normal working condition by relying on the force of the spring.
