IV.  Working Process and Principle

The feeler lever contact with coal if there are coal on the belt, and the angle of inclination reach to action angle, the sensor takes action. The feeler lever comes back to initial angle if there are no coal on the belt, and the contact of sensor resets.

The following drawing is its electrical schematic diagram.

V. Installation and wiring

Install the sensor on the beginning of the conveyor, the feeler lever is vertical to the center of the belt, and it is 20mm above the belt. The material flow sensor should send out start signal when there are coal comes out, and machine vibration should not make misoperation, it should not be damaged by anything big, so a certain height is required to the installation, and the frame should have mechanical strength, installation should be carefully adjusted repeatedly to make it sensitive and reliable, the wire end must be wrapped by plastic tape. .

Cable outer diameter φ8~φ12( or communication cable is available), not less than 2.5mm².

 

VI. Usage attention

1. The structure and every electrical parameters of the sensor have been debugged before leaving the factory, the user shall not change its structure and electrical parameters at will to ensure the performance of protection, explosion-proof and intrinsically safe. This product can only be used with designated device, or the devices have explosion proof tested.

2. The start and stop control of the conveyor is determined by the sensor, and the sensor is installed after debugging, the working condition of the sensor directly determines whether the deviation protection of the control device can work, and the non-professional personnel is not allowed to take off or install the sensor.

3. The maintenance personnel should regularly check the condition of each part of the sensor, the problems must be dealt with in time.

4. The improper changes of internal components wiring may cause equipment damage, our company does not bear the liability and economic losses caused by above-mentioned accident.

5. The packing carton can be used for all kinds of transportation including land and water under the condition of avoiding direct rain and snow.

6. The packaged device can be stored in the warehouses with air circulation, the temperature is (-10~40), relative humidity not over 90% for more than 12 months.

7. Take out the packing list and compare with each item to confirm the conformity.

8. To check the nameplate on the sensor is comply with the order requirement.


Huafei Company could provide Different Kinds Of Sensors,such as complete Automatic Control SensorMining Temperature Sensor for belt conveyor, Belt Conveyor Safety ProtectionBelt Conveyor Sensor, belt conveyor automatic control sensor, Explosion Proof SensorBelt Conveyor Sensors and other Belt Conveyor Safety Protection.
