Although they are all metal substances, there are differences in the detection of different types of metals by metal detectors, and some metals are not easy to be detected. For example: conductive and magnetic metals, iron, chromium steel, carbon steel, and tungsten carbide are the most easily detected metals because they have a significant effect on the magnetic field of the metal detector. The same is true for other low-resistance non-ferrous metals, such as copper, aluminum, lead, brass, bronze and so on. Although they are not magnetic, they are conductive and easier to detect. Only those pure, high-resistance and non-magnetic metals, such as 304 and 316 in stainless steel, pose the greatest challenge to metal detectors. They have poor conductivity and are difficult to detect, but they are often used in food and packaging machinery. But as long as the detectors perform well, they can still be reliably identified. In order to obtain the detection effect of a metal detector, choosing the correct location for it is as important as choosing a good machine as much as possible. Although many times when the plan device re-production line is considered to equip the metal detection system, the existing production line requesting the detection machine can also be troublesome to install in the original production line. Most food and drug consumers install metal detectors at the end of the consumer line to make final inspections of goods before they are shipped to wholesalers and customers. However, from the perspective of cost, it is more valuable to stop earlier detection of contaminants, because the waste is only low-priced ingredients, not packaged waste. The ideal location of the metal detection system varies with the product and industry, and varies from factory to factory. For most consumers, if the metal detector is installed in a relatively forward-facing process in the production line, limited space is often a problem. Placed above the bag making machine and packaging machine. Most consumers can configure the system according to the customer's request for space. Liquid products, such as soup or pie filling, can be detected online by the pipeline detector, and then the pipeline connected to the processing equipment carries the product through the detector. Manufacturers of metal detectors should be able to provide accessories that connect the equipment to any processing equipment. The type of pipe required depends on the temperature, flow rate and product viscosity, but it must be made of non-metallic materials.
