If viewed from a technological point of view, metal detecting device based on electromagnetic background formed by installing a different metal objects when used in an electromagnetic environment. The secondary electromagnetic background vary in density, and other characteristics. These properties depend on the size of the object and its conductivity (in gold and silver metal conductivity is considerably higher than in the lead) no doubt-from the distance between the antenna and the device object (the distance from the surface).
Cartographic techniques identified the metal detector. The four main node includes: antenna (in some cases there are differences between mobility and receiving antennas, and sometimes the same antenna); processing site information provided; data node views (information on screen-LCD or needle piercing lap speaker or headphones) and the power supply unit.
Search metal detectors
The metal detectors used to explore various metal objects. This is usually the largest, most expensive and least sophisticated, able to carry the maximum number of jobs. He knows the fact that sometimes you need to find objects in the ground at a distance of up to several meters.
Antenna can generate high levels of electromagnetic background, and with great sensitivity to detect even very small sources of electric field at large distances from the surface. In particular, one consider detector capable of finding a metal object with one coin at a distance of up to 3 meters in the ground, filled with rocks and iron.
In addition, this metal detectors able to distinguish what type of metal of this topic, as well as almost as indicating the distance from the surface location of the object. It may seem unrealistic, but the fact remains uncertain.
Search metal detector application validation service at customs checkpoints, security services and the military unit for detecting mines and other explosive objects. Scientists and archaeologists and treasure-hunters using metal detectors to search for valuable historical artifacts. Finally, as a group, looking for the lost metal objects in the ground. The reform and construction crews used the device to detect underground lines for metal detectors or networks (pipelines and high voltage cables). Not all the ways to use search metal detectors.
Search for GPS is a narrow range of metal detectors, which use their specialized military units, border guard Brigade and all types of organizations, ranging from Boutique to government agencies. Their research purpose mineral elements prohibited transfer or use. Especially the different weapons, jewels, explosives and others that might be hidden under clothing or luggage. Custom metal detectors are small and easy to use. The number of requirements, including: vibration handles, after detecting the maximum metal coins-up to 10-15 cm).
It is very popular among the security services that somewhat metal detectors associated with bow, is walking through the detection of solids. For the vertical sensors are very sensitive side frames, metal objects which are at different levels. Often installation is required in banking or Government offices, airports, train stations, and areas designated for public events. Metal detectors (adaptation) and the maximum speed for inspection when going through people.
Metal detectors for building and repair work. This type of metal detectors, under sound and light alarm will tell workers where partition wall or panel mounted wires or pipes made of metal and features a design or other metal objects. Needless to say that metal detectors cannot detect if anything more of these items along the wall is metal mesh or sheet metal.
Certain types of metal detectors, specialized for reform and construction, often integrated in one structure with the qualifications for details of wood, that the current level of effort in the playoffs carrying wires, leak Filtration’s etc.
