Brief Introduction of 1. Underground Metal Detector

The underground metal detector is made of advanced technology. It has the characteristics of wide detection range, accurate positioning, strong resolution and convenient operation. Underground metal detectors are mainly used to detect and identify buried metal objects. In addition to military applications, but also widely used in: security, archaeology, prospecting, looking for scrap metal. Also known as "iron detector", is a good helper for waste recycling.

Underground metal detectors use the principle of electromagnetic induction, the use of alternating current through the coil to generate a rapidly changing magnetic field. The magnetic field may induce eddy currents inside the metal object. The eddy currents generate a magnetic field, which in turn affects the original magnetic field, causing the probe to chime.

The metal detector door and handheld metal detector in the airport security inspection area can not only detect weapons and metal instruments, but also detect metal objects such as coins and keys. Therefore, it will check whether there are metal objects such as knives at airports and other places.

Metal detectors are also used in many industries, such as food and plastics, to detect metals in products. In order to improve the purity of the product, to prevent debris mixed.

The underground metal detector uses the principle of electromagnetic induction to generate a rapidly changing magnetic field by using a coil through which an alternating current passes. The magnetic field may induce eddy currents inside the metal object. The eddy currents generate a magnetic field, which in turn affects the original magnetic field, causing the detector to sound a beep. It is made with advanced technology. It has the characteristics of wide detection range, accurate positioning, strong resolution and convenient operation. Underground metal detectors are mainly used to detect and identify buried metal objects. In addition to military applications, but also widely used in: security, archaeology, prospecting, looking for scrap metal. Also known as "iron detector", is a good helper for waste recycling. The area, shape and weight of the metal to be detected have a great relationship. Generally speaking, the larger the area, the more the number, the greater the corresponding detection depth; on the contrary, the smaller the area, the less the number, the less the corresponding depth. Smaller. The detection depth listed in the table below is the result of the actual measurement using 60cm x 60cm 0.5cm aluminum plate embedded in dry soil according to the product enterprise standard.

Main functions

The underground metal detector is equipped with a grounding balance circuit, which can eliminate the influence of "mineralization reaction" and greatly improve the depth and accuracy of effective detection;

having the function of distinguishing between ferrous metals and non-ferrous metals;

The underground metal detector adopts intelligent operating system;

Underground metal detector adopts high strength ABC material package, light weight, long life;

Metal sounds can be recognized by headphones.

Underground metal detector is a detection instrument manufactured by advanced technology. It has the characteristics of wide detection range, accurate positioning, strong resolution and convenient operation.

It can also be used as a tool for teenagers to carry out national defense education and popular science activities, and of course it can be regarded as an interesting entertainment toy.
