Metal detector doors are divided into handheld and portable, so are the two types of metal detection devices that have very different appearances in principle the same? What is the detection principle of a hand-held metal detection door? Today Xiaobian security experts do a simple analysis for you.
First of all, what type of metal detector door we are talking about is that, except for the SMD601 model, the imported metal detector door can detect copper. Other similar devices use the principle of magnetic field induction, which means that their principle is the same. The above-mentioned two products are based on chromatographic analysis principles and also assist magnetic field sensing technology.
Second, the detection principle of portable metal detection doors is also magnetic field sensing. Compared with underground detectors, hand-held devices are close-range detection instruments. Therefore, their detection sensitivity is very high, and they are mainly used for close-in inspections. For example, airports use PD140 for security. Inspection, the use of the station to use the GC-1001 for security detection, is a reason, but the gap between the performance of the product is good or bad. In the use of metal detection doors and detection parameters!
Metal detection experts believe that each type of detector has been developed and designed into a variety of different appearances because of the different locations and different uses. In fact, the metal detection gate is also a kind of detector, but its independence is defined as passing metal. Detection door, the principle is to use metal detection technology.
