1.Overview 1.1.GVD300 mining intrinsic safety tear sensor is suitable for underground coal mine, open-pit coal mine, coal preparation plant and other workplaces, as the belt conveyor belt longitudinal tear protection.
1.2.Explosion proof type: mine intrinsic safety type; explosion proof sign: Exib I.
1.3.Environment condition
1.3.1.Atmospheric pressure: 80 kPa ~ 110 kPa;
1.3.2.Ambient temperature: - 20 ºC - 40 ºC;
1.3.3.Relative humidity < 96% RH (25 ºC);
1.3.4.Underground coal mine with explosive mixture of methane and coal dust;
1.3.5.There is no gas enough to corrode and destroy the metal shell and electrical insulation;
1.3.6.No immersion of water or other liquids;
1.3.7.In the environment without strong vibration and shock.
2.Structural characteristics and working principle 2.1 Structural features: good sealing performance and convenient maintenance.
2.2 Working principle:
When the belt conveyor works normally, the sensor enters the detection state. When the tape is not torn, the two output terminals of the sensor are disconnected. When the tape is torn, the two output terminals of the sensor are connected. The main machine of khp143-z mining belt conveyor protection device sends out belt tearing signal and alarm, and delays 1 s ~ 2 s to control the belt conveyor to stop.
3.Functional features 3.1. The product has the advantages of simple wiring, less explosion loss points and easy maintenance;
3.2. Mine intrinsically safe tearing sensor has high sensitivity;
3.3. The product has good sealing, moisture proof, simple and reliable operation and small maintenance.
