The metal detector is a widely used detector. There are three main categories: electromagnetic induction type, X-ray detection type, and microwave detection type. It is an electronic instrument used to detect metals and can be used in many fields.

In the military, metal detectors can be used to detect metal mines; in the security field, they can detect weapons and crime tools that are carried or hidden; in archaeology, they can detect ancient tombs with buried metal objects and find gold and silver treasures in ancient tombs. And jewelry or other metal products; in engineering, it can be used to detect underground metal buried objects, such as pipelines, pipelines, etc.; in mineral exploration, it can be used to detect and discover natural gold particles; in industry, it can be used for online monitoring, such as removing cotton , Coal, metal debris in food, etc.

This passage is going to talk about the followings of what can walk through metal detectors detect: 


Application fields

Security inspection



Compared with traditional detectors: the working surface of the metal detector detection area adopts a special design, with a large detection area, fast scanning speed and extremely high sensitivity. The shell is made of ABS engineering plastic at one time, with strong resistance, fine craftsmanship, light weight and easy portability. It can detect all kinds of metal objects hidden on the human body, including jewelry, electrical components, etc. It is suitable for use in airports, customs, docks, banks, buildings, prisons, stadiums, hospitals, schools and other places. This product uses large-scale integrated circuits, can be fully equipped with 9V rechargeable batteries (optional), low-voltage indicators, LED lights and sound alarms and vibration alarms. It is a rare ideal product for checking illegal items. 


Application fields

Metal detectors for the food industry

In the food industry, metal detectors are mainly used to detect metal impurities. There are two types of metal detectors for food: belt type and pipeline type. The belt type is a conveyor belt. Put the food on the belt and pass the probe if it contains metal impurities, it will alarm and stop or remove it. The pipeline type is mainly a free-falling type, where the food falls freely, and the probe will alarm and then be discharged.

Application of metal detectors in other industries

Textiles (food, medicine, clothing, apparel, toys, shoe materials) inspection and broken needles.

The special name is: needle detector, needle detector.

For security and anti-theft inspection

The special names are: metal detection door, security door, metal detection security door.


Security inspection

In security inspections, as with the development of other uses of metal detectors, both AC and pulse systems are used, and the design of coils and electronic equipment is also moving forward to improve the discrimination of these systems. The metal detector can indicate the approximate height of the metal object above the ground, so that security personnel can locate the signal source faster. Smaller hand-held metal detectors are also used to more accurately locate metal objects on people.

In civil engineering, special metal detectors (covering tables) are used to locate steel bars in walls.
