Practical application case of metal detector

Our food production enterprises will encounter some problems in the normal production process, of which Zui's main problem is that there may be some metal impurities in the production, which will bring great trouble and economic loss to our food production enterprises The metal detector which can detect the metal impurities is produced With its wide application in our production enterprises, it can ensure that the food products do not contain metal pollutants, improve the production efficiency of enterprises and reduce the labor intensity of workers According to the actual application of metal detector, its classification is different However, these different kinds of metal detectors are based on the measurement of conductivity and magnetic field to detect metal The sensitivity of the detector decreases with the increase of detection range The size of the induced signal depends on the size and conductivity of metal particles According to the different use range of metal detector, the metal impurities it can detect are also different Many inspected products have one of the characteristics or both For example, our agricultural crops are products with high iron content, which can generate strong magnetic signals However, our metal detector must solve this problem to detect small metal objects, and these products are classified as "dry" products In addition, some foods we often use in our real life, such as bread, meat, cheese and other products with high moisture and salt content, are conductive in themselves, which will produce misleading signals, which are classified as "wet" goods Above, I give a brief introduction to the working principle of the metal detector, and make a simple explanation according to its classification With the needs of our production enterprises, metal detector is widely used in all fields of our society.
