Mine with GEJ30 deviation of the sensor, deviation protection deviation switch, deviation controller 

 (The original Model KGP-2) deviation of the GEJ30 sensors are suitable for explosive gas mixture of methane dangerous places, as well as surface mine, coal preparation plant in the workplace, as the mining belt conveyor protection devices supporting inspection. Monitor the deviation of the conveyor belt conveyor belt conveyor belt running side, the sensor output low-level signals, the protection device after a delay, cut off the conveyor to control power to achieve deviation protection, sensors install an unlimited number and are connected in parallel. 
 Explosion-proof type 
 The mine Intrinsically Safe, Explosion-proof mark "ExibI; 
 Dimensions: 350mm × 165mm × 65mm; Quality: 3kg. 
 Action angle of 30 ± 3 ° 
 Touch lever action force: 20 ~ 100N. 
 Reset angle of 15 ° 
 Probe rotation limit angle is not less than 70 °. 
 Contact resistance 
 Closed contacts of the contact resistance less than 0.1Ω, vibration, shock, and after life test is not greater than 0.2Ω. 
 Working principle 
 The sensor is installed in the belt on both sides of the bracket, the belt does not touch the normal deviation touch lever, the two terminals of the sensor is not connected; 
 When the belt deviation contact to the deviation touch rod and to promote the touch rod 30 ° ± 3 ° deviation from the normal position, the sensor's two terminals connected. 
 Belt after reset 
 Deviation touch lever automatically returns to 15 ° ± 3 °, the two terminals of the sensor should be disconnected. 
 Installation 
 Sensor is mounted on the belt on both sides of the bracket, open the sensor junction box cable (deviation signal), O (power ground) 
 Connected to the corresponding terminals on the belt conveyor protection device host. 
 Debugging 
 Gently push the sensor coal-touch lever to deviate from the normal position of 30 ± 3 °, the two terminals of the sensor should be on, release, 
 Coal-touch lever automatically returns to 15 ± 3 ° when the two terminals of the sensor should be disconnected.
