Metal Detector Knowledge Science

Metal detectors today fall into several major categories. Metal detectors can be used to detect metal mines in the military. In the security field, weapons and tools for carrying or hiding can be detected. In engineering, underground metal can be used to detect Buried materials, such as pipelines, pipelines, etc.; can be used to detect and discover natural gold particles in mineral exploration; industrially, it can be used for on-line monitoring, such as removing cotton, coal, and metal impurities in food.

All-metal detector: can detect all metal impurities of different materials, so this product is currently in the global market, the highest share, but also more loved by various users. And this product is widely used, mainly used for iron, metal and non-ferrous metals in foods such as meat, fungi, candy, beverages, food, fruits and vegetables, dairy products, aquatic products, health products, additives and condiments. Detection of metal impurities. Metal impurities used in chemical raw materials, rubber, plastics, textiles, leather, chemical fiber, and toys are used to detect metal impurities in pharmaceuticals, health products, biological products, cosmetics, gifts, packaging, and paper products.

Iron metal detectors: iron metal detectors, also known as "needle detectors", "needle detectors" and "needle machines". These types of products can only be used to detect iron and metal impurities. They are mainly used in clothing, textile and other sewing products industries. It is used to detect broken needles in the leftover products in the production process of sewing products. Special reminder: The needle detector cannot be used in the food industry, because the needle detector mainly depends on the physical magnetic field and the electromagnetic field magnetic detection (the probe of the needle detector is a magnet inside), and the sensitivity of the needle detector will decrease with the magnetism of the magnet. Lowering, so this equipment has a shorter life span, together with the needle detector can only detect iron metal, and now the market is facing a situation of elimination.

Aluminum Foil Metal Detector: Aluminum Foil Metal Detector: It is mainly used for detecting aluminum film or aluminum platinum packaging products. Many of the medicines used in the production process are packed in aluminum foil or aluminum foil and can only be tested using such equipment. At present, the technical level of this product is relatively high and the price is relatively expensive.

Hand-held metal detectors: They are used in airports, workshops, docks, public transportation, and public safety inspections of stadiums. The industry is mainly used to prevent the loss of products with extremely high levels of metals. In recent years, the Chinese market has also been used in various examinations. Prevent candidates from violating discipline. Such as college entrance examinations, postgraduate exams, civil service exams, etc.

Underground metal detectors: minesweeper applied in the military, exploration of archaeological artifacts, exploration treasures in the adventure. Nowadays, underground metal detectors are mainly used for the detection of metallic materials. At present, there is an exploration army that uses underground metal detectors to detect and excavate scrap metals.

Conveyor type metal detectors: mainly used for detecting small volume products, as well as small bags, boxed industrial products, can be connected to the production line, and achieve linkage. It is currently the most widely used domestic product.

Drop-type metal detectors: mainly used to detect powdery, small-grained granular products. Mainly used in plastics, rubber industry

Pipeline metal detectors: mainly used to detect the paste, seal the pipeline on the pipeline. It is convenient for the detection of metal impurities in pipes. It is mainly used for the detection of tablets, capsules, granular (plastic particles, etc.) and powdered articles.
