How metal detectors work
Metal detector is the abbreviation of metal detector, mainly for professional personnel. Metal detector is used to detect foreign metal objects mixed in the production process of food, medicine, cosmetics, textiles, etc. The principle is a central emission coil and two two equal receiving coils, the three coils are housed in a probe. The oscillator emits a high-frequency magnetic field through the transmitting coil in the middle, which is connected to the two receiving coils, but with opposite polarities. When the magnetic field is not disturbed by the outside world, the voltage output signals generated by them cancel each other out. Once metal impurities enter the magnetic field, this balance is disrupted, and the metal detector can detect the presence of metal. Usually the metal detector consists of two parts, namely the metal detector and the automatic rejection device, of which the detector is the core part. Three sets of coils are distributed inside the detector, namely the central transmitting coil and two equal receiving coils. The oscillator connected to the middle transmitting coil generates a high-frequency variable magnetic field. In the idle state, the induced voltage of the receiving coils on both sides is generated. Before the magnetic field is disturbed, they cancel each other out and reach an equilibrium state. Once the metal impurities enter the magnetic field area and the magnetic field is disturbed, this balance is broken, and the induced voltages of the two receiving coils cannot be canceled. ). The system can use its alarm signal to drive an automatic rejection device to exclude metal magazines.
