specification
GEJ30 (the original model KGP - type 2) wandering sensor applies to have.. Sex mixed gas of methane and open-pit coal mine, coal preparation plant and other dangerous places, workplace as mine belt conveyor protection device of form a complete set of detection. For belt conveyor belt running deviation of condition monitoring, when the belt conveyor's belt running deviation, low level signal of sensor signal, protection after a delay, to cut off the conveyor control power, achieve partial protection, sensor installed an unlimited, and all are connected in parallel
Explosion-proof type: mine intrinsically safe explosion-proof marks "ExibI";
Shape size: 350 mm * 165 mm * 165 mm; Quality: 3 kg.
30 + 3 ° Angle, feeler lever action force: 20 ~ 100 n.
Reset Angle is 15 ° and the limit of the rotary Angle of sheath maerial of not less than 70 °.
Contact resistance: closed contact contact resistance is not greater than 0.1 Ω, vibration, shock, and not more than 0.2 Ω after life test.
principle of operation
Sensor installed on the belt on both sides of the bracket, normal belt out of touch with wandering touch rod, the sensor of two terminals is not connected;
When the belt running deviation in contact with the wandering touch touch rod and push rod deviates from the normal position to 30 ° + 3 °, two terminals connected sensor.
Installation: install the sensor on the belt on both sides of the bracket, open the sensor junction box, cable will E (running deviation signal), O (power supply)
Debug: touch of coal. Gently push the sensor bar to deviate from the normal position 30 + 3 °, two terminals should be connected to sensors, loosen
