Do you know about metal detectors?

With the rapid development of social economy and science and technology, the metal detector, a device that can perform people screening, has undergone several generations of detection technology changes, from the initial signal simulation technology to continuous wave technology, to the digital pulse technology used today, metal. The detector introduces a variety of scientific and technological achievements based on the principle of simple magnetic field cutting. The application field has also been extended to multiple industries with the improvement of product quality. So, do you really understand the metal detectors that can be used for people screening? Can it only be used for people screening? The following article gives a brief introduction to the metal detectors that can be used for people screening.

The main points are as follows:

What is a metal detector

Metal detector is a kind of equipment with high performance and security design that can do people screening. It mainly has three categories: electromagnetic induction type, X-ray detection type and microwave detection type. It is an electronic instrument used to detect metals and has been widely used in various fields.

Classification of metal detectors

1. Market by function:

① All-metal detector: it can detect all metal impurities of different materials,  mainly used for:

A. It is specially used for the detection of iron metal and non-iron metal impurities in meat, candies, fruits and vegetables, dairy products, aquatic products, health products and condiments.

B. Used for testing metal impurities in chemical raw materials, plastics, textiles, leather and toys .

C. Metal impurities in medicine, health care products, biological products, cosmetics, gifts, packaging and paper products.

② Iron metal detector, this kind of products can only be used to detect iron metal impurities, mainly used in garment, textile and other sewing products industry, used to detect broken needles in products left in the production process of sewing products.

③ Aluminum foil metal detector: mainly used to detect aluminum film or aluminum platinum packaging products.

2. Classification by use:

① Hand-held metal detector:

It is applied to public security check in airports, workshops, venues, etc., which is the most extensive use of the people screening work.

② Underground metal detector:

Mainly used for the detection of metal materials.

③Plate metal detector: it is used to detect thin products such as sheet and filaments.

In addition, there are falling, conveyor and other metal detectors that can do people screening.

Applications of metal detectors

1. Food industry

Metal detectors are mainly used in the detection of metal impurities in the food industry. There are two kinds of metal detectors for food: belt type and pipe type. Belt type is the conveyor belt, put food on the belt through the probe if there is metal impurities will alarm stop or eliminate. Pipe type is mainly free-fall, food free fall, after the probe will alarm and then discharge.

2. Application in other industries

For security and anti-theft inspection, its special name is: metal detection door, security door, metal detection security door

Conclusion

At present, domestic metal detectors can only detect metal objects, while non-metallic dangerous objects like drugs cannot be detected, so they can't do people screening perfectly. But we firmly believe that as long as we work hard to develop, we can introduce advanced metal detectors with international standards as early as possible.
