GEJ30 switch -GEJ30 deviation sensor -GEJ deviation switch

GEJ30 switch -GEJ30 deviation sensor -GEJ deviation switch GEJ30 Mine deviation sensor is intrinsically safe electrical mining equipment for coal mine gas and coal dust hazardous environments. And KHP128-Z Mine conveyor protection device host supporting the use of conveyor belt run is used as detection and protection. 1.3 Explosion-proof type is: mining intrinsically safe explosion-proof mark: ExibI 1.4 Environmental Conditions 1.4.1 The deviation of the sensor should be able to work properly in the following conditions: Ambient temperature -20 ~ + 40 ℃; average relative humidity: no more than 95% (25 ℃); atmospheric pressure 80 ~ 106kPa; Vibration: acceleration 50m / s2; Impact: Peak acceleration 500 m / s2; coal mine without damage to the insulation corrosive gas; 1.4.2 deviation sensor can withstand Storage worst weather conditions: - temperature: + 60 ℃; - low temperature: -40 ℃; - average relative humidity: 95% (+ 25 ℃). 2 GEJ30 switch -GEJ30 deviation sensor - 2.1 Structure and working principle structural features: small size, light weight, good sealing performance, easy maintenance; after contact action also left a large buffer probe rotation angle, making itself easily damaged; scroll jacket fitted on the probe, to avoid friction between the probe and tape. 2.2 works tape during normal operation, deviation switch probe in a vertical position. When the belt run, tape encountered probe deviation switch and drive axis probe, when the probe deflection to a certain point, toggle switch deviation within the limit switch, issue deviation signal. 3 GEJ30 switch -GEJ30 deviation sensor - the main performance 3.1 Contact capacity: DC12V / 0.5A; for qualified by testing intrinsically safe circuits; 3.2 output contact form: a pair of normally open 3.3 Weight: 3kg 3.4 Dimensions: 380mm × 170mm × 72mm 3.5 operating angle: 30o ± 3o 3.6 Operating force contact bar: 20N ~ 100N 3.7 reset angle: 15 ° ± 3 ° 3.8 probe rotation limit angle: ≥70 ° 3.9 Housing Protection grade: IP54 4 GEJ30 switch - GEJ30 deviation sensor - mounted 4.1 installation deviation sensor mounted on the conveyor frame, pay attention to adjust the deviation of the sensor probe and the tape position. 4.2 Wiring the user can select the cable diameter needed 6 ~ 12mm of mine rubber cables 3 × 1.5, the deviation of the sensor output contact leads to a coal mine belt conveyor protection device host control on the contacts. 4.3 Considerations a. Can only be used by the inspection of intrinsically safe explosion-proof circuit. (Warnings) b. Rated voltage power supply and use the nameplate on the line with c. When not in use, the line must be required to block the mouth
