As consumers have higher and higher requirements for product quality, in order to ensure product quality and safety, many factories will use metal detectors to detect metals during product production or before leaving the factory to ensure that no metal foreign matter is mixed. In the process of using metal detectors, we often encounter the problem of false alarms. According to the use of hundreds of customers, after eliminating the quality problems of the machine itself, our company has summarized the following common causes of false alarms:

1. The foot is not placed smoothly, the machine will shake

2. Too much dust inside the detection head

3. The conveyor belt is too dirty or mixed with metal impurities

4. The selection of the equipment channel is not suitable, and the product hits the detection head when passing through

5. There is interference in the power supply, unstable voltage or static electricity, etc.

6. Interference from surrounding high-power electrical equipment

7. Multiple metal detectors are used side by side, with the same frequency interference

8. Metal interference worn by the operator, mobile phones, keys, etc.
