Mine entrance metal detection security gate

When purchasing security screening gates, you need to consider the seismic resistance: the door body cannot ring continuously when it shakes. The stability and anti-interference ability of a security screening gate directly affect the normal use of the security screening gate. Some companies and users did not pay attention to relevant aspects when purchasing security screening gates or were deliberately avoided by some manufacturers. As a result, the stability of the purchased security screening gates was very poor, and false alarms continued whenever there was any disturbance, seriously affecting normal use. Based on the principle of magnetic field induction at the security screening gate, when the magnetic field of the security screening gate vibrates, it is easy to cause false alarms. A high-quality security screening gate should not cause false alarms even if the magnetic field oscillates when no one passes through (such as strong wind blowing or the door panel shaking). When someone happens to be passing by when the magnetic field oscillates, it must be ensured that it returns to normal quickly, instead of giving false alarms all the time.

When purchasing security inspection machines, pay attention to stability: carry a pin in the middle of the door and it should ring once every time you walk. There should be no omissions or false alarms. When the security screening gate of poor quality is close to its sensitivity limit, it will sometimes alarm and sometimes not alarm, and if it is placed in the third zone, it will display the alarm in the fifth zone.

Detection effectiveness: The security gate has the function of automatically counting the number of people passing through and the number of alarms. If the displayed number of people does not match the actual number of people passing through, it may result in false negatives, which means there are loopholes in the security check. A good security screening gate should be able to detect it a hundred times after one hundred passes.

When purchasing security screening gates, you need to pay attention to sensitivity: pins can be detected in the middle of the door. Since the principle of the security screening gate is that when a metal object passes through the magnetic field generated by the pillars on both sides of the door, it will cause magnetic field induction and alarm. This will inevitably lead to the phenomenon that the sensitivity will decrease from both sides of the door panel to the middle area, that is, the sensitivity on both sides close to the door panel will be higher than in the middle. Many security screening gate manufacturers now claim to be able to detect metal the size of a paper clip, but in fact many security screening gate manufacturers can barely detect it only when they are very close to the door panels on both sides, and there is no response at all in the middle. It is necessary to be able to detect small pieces of iron metal when removing belt buckles, and to detect controlled weapons and firearms when removing belt buckles, keys, mobile phones and coins.
