How to choose security door based on sensitivity?

  Generally speaking, the traditional X-ray security door can detect all metals, and must pass the strict inspection of the "Sensitivity" standard in the GB15210-2003 national standard. Therefore, we hope that the metal samples selected for detection can be preferably included in the scope of national standards.

  The ability to detect metal signals can be used as a sign of the technical strength of manufacturers of safety inspection doors. If the manufacturer is good at technology, it can naturally perform the same tests on non-ferrous metals and ferrous metals. At the same time, in the case of good stability, smaller metals will be detected, and the sensitivity control is also very clear. However, if the sensitivity of the poor quality security inspection door is slightly increased, then even if nothing passes, it will randomly give an alarm. If the sensitivity is slightly lowered, a large amount of metal will be needed to make an alarm.

   In addition, electromagnetic waves are directional, so the detection of metal objects is also directional. The signal generated by the surface with the most electromagnetic waves is correspondingly stronger, while the signal generated by the surface with the least electromagnetic waves is naturally weaker. If it is an excellent production company, the directionality of the magnetic field can be uniformized, and there is almost no difference in the effect of detecting metal objects in all directions in the same detection area of this security inspection door. In this case, the greater the difference, the easier it is not to report.

   Therefore, when testing the security door, x-ray security equipment manufacturers try to choose the same metal object to be carried by the tester through each position of the security door, and at the same time pass the metal object in different directions in each position in order to select products with less omission .
