GVD1200 tear sensor, GVD300 tear sensors, longitudinal tear detection device, GVD30, GVY1 belt 1. Overview GVD1200 tear tear sensor sensor for coal mine methane and other explosive atmospheres, as belt conveyor belt tear detectors protection, but also with the ground, mining, coal preparation plant, cement plants, power plants, ports and other belt conveyor machines. 1.1 Standard: 1.2 Explosion-proof type: Mine intrinsically safe type. 1.3 Explosion-proof mark: "ExibI Mb", product compliance GB3836.4-2010 simple device. 1.4 Work: continuous work. 1.5 Dimensions: 1000mm × 300mm × 30mm weight ≤8Kg. 2. Environmental conditions 2.1 environment a) Ambient temperature: (0 ~ 40) ℃; b) Humidity: ≤98%; c) atmospheric pressure: (80 ~ 116) kPa; d) wind speed: ≤8m / s. 2.2 Transport and storage conditions a) Temperature: (- 40 ~ 60) ℃; b) Vibration: ≤50m / s2; c) Impact: ≤500m / s2. 3. Main function and technical parameters 3.1 Output signal: passive switch; 3.2 Contact capacity: DC24V / 0.2 A (resistive load); 3.3 contact resistance ≤0.1Ω; vibration, shock after the test ≤0.2Ω; 3.4 Action Performance area of ??the pressure-sensitive sensor tear 3000cm2, when it falls on a 100cm2 at 1200g material, sensor operation output contact closure. 3.5 operating value tolerance range of the sensor operation error ± 10%. The operation principle of the sensor in the material falls on the sensor 1200g 100cm2, sensor immediate action, normally open contact closure, after the material is clear, normally open contact off immediately. 5. Installation using cable outer diameter of φ6 ~ φ10 (also with communication cables), not less than 2.5㎜2. Tear sensor is placed between the upper and lower tape, horizontally positioned between two rollers, the belt when not met the loosest appropriate. The rope on the sensor is fixed to the sides of the belt conveyor steel beam or bracket. Also homemade bracket. When Caesar coal tear tape to the sensor, the sensor operation output devices to the association. When the tape is torn edges sagging phenomenon, due to the sagging tape scratching the sensor may cause protective device downtime. Main: safety monitoring system and supporting sensors, portable security detection equipment, protective life-saving equipment, mining equipment and related accessories. Denway Jining Mining Equipment Co., Ltd. is located in Jining City, Shandong Province, Tang Industrial Park, new and old customers call to plant inspection.
