Metal detectors or sources in metal detection must have the ability to identify new metals, detecting metals at the surface and depth depends on the type of detector, which is a metal detector, manual ground radar, magnetic or frequency mineral detector.
The working principle of the metal detector, if it is of the separate category, is to separate metals and gold or the electric charge of other sources, and detection in detectors is divided into difference detection and separation, which is the difference detection of separating ferrous metals from non-ferrous metals.
which is related to the performance of magnetic metal detectors such as pulse or VLF or TR… and the separation is related to the separation of metals or gold according to the VDE number.
Division by output
Due to the ever-increasing progress of the metal detector manufacturing industry and their diverse applications in various fields and sciences, each metal detector is presented with its own unique manufacturing technology. Here we review the systems and technologies used in these devices.
- analogue
- Digital
- visual
Analog metal detector
The analog metal detector identifies the material through the frequency it sends to the ground and receives from the ground.
Digital metal detector
The digital metal detector has a digital screen and is able to separate and determine the size. In the digital version, loop and disk are used.
Video metal detector
Image metal detector is able to edit the image inside the ground. For example, if there is a statue inside the ground, it shows the shape of the statue. They are visually capable of identifying the cavity of caves and so on.
