What is the principle of underground metal detector?
The underground metal detector is a detection instrument made with advanced technology. It has the characteristics of wide detection, accurate positioning, strong resolution, and easy operation.
It is mainly used to detect and identify metal objects buried underground.
working principle
A metal detector is an instrument specially designed to detect metal, except for mines with metal casings or metal parts;
It can also be used to detect hidden wires in walls, buried water pipes and cables;
You can even go underground and find metal objects buried in the ground.
The metal detector can also be used as a tool for youth defense education and popular science activities, and of course it is also an interesting entertainment toy.
Metal detectors mainly use these principles:
High Frequency Oscillators, Oscillation Detectors, Audio Oscillators, Complementary
In addition to its military applications, it is also widely used in:
Safety inspection, archaeology, prospecting, looking for scrap metal. Also known as "iron detector", it is a good helper for scrap recycling.
The treasure digger adopts sound alarm and instrument display, and the detection depth has a great relationship with the area, shape, weight and year of the metal to be detected;
Generally speaking, the larger the area, the greater the number, the farther the year, and the greater the corresponding detection depth; on the contrary, the smaller the area, the smaller the number, and the smaller the corresponding depth as the year progresses.
