GUJ30 Coal mine of sensors

GUJ30 mine sensor for pile of coal mine intrinsically safe electrical equipment, suitable for coal mine gas and coal dust explosion dangerous environment. With KHP128 Z type coal mine belt conveyor comprehensive protection device, used for belt conveyor of coal detection and protection.

performance characteristics

This sensor is a mechanic. CAM mechanism is adopted and torque amplification principle of omnidirectional, action quick, can in dry coal, water, coal and water spray to work normally. When there is a conveyor buried the nose, full, full of coal hopper, coal coal hit a contact position transducer and facilitate touch rod swinging Angle of deviation between the center line of action more than 30 ° plus or minus 3 °, sensors, this sensor can automatically cut off the voltage is implemented coal conveyor protection.
