The ability of Walk-through metal detector on security inspection of metal objects

Select the same metal sample to detect the gate, the smaller the better.

Traditional safety doors should be able to detect all metals (except for specially designed detectors), and all metals can be tested in strict accordance with the [sensitivity" standard of the gb15210 - 2003 national standard.

The metal samples we choose are best included in the national standard.

Metal signal detection capability is the hallmark of the Metal Detector manufacturer's technical strength. Manufacturers of non-ferrous metals and ferrous metals are able to perform the same detection, stability and good conditions to detect small metals, and the sensitivity control is clear. If the quality of the poor quality is slightly higher, when the sensitivity is high, nothing can cause an alarm, the sensitivity will be lower, and the metal can be used to alarm.

This kind of safety door is due to poor internal circuit design, and the control is not linear and cannot be used.

In addition, due to the direction of the electromagnetic waves, the metal detection is oriented, and in order to reduce the electromagnetic wave signal corresponding to the most powerful surface, the minimum surface-cut electromagnetic wave signal is correspondingly weakened. A good manufacturing company can handle the directionality of the magnetic field. Therefore, the effect of detecting a metal object in the same detection area is not different. If the difference is larger and the omission is greater, then the user should choose a product with good direction detection.

The same metal object is selected by the tester to pass through the various locations of the security door, and the metal objects are passed in different directions in each location, and the products with less false negatives are selected. For the elimination of small metals, it is necessary to adjust the sensitivity to a suitable position when detecting a large metal. The test method is the same as above.
