Food metal detector principle

Application of the principle of electromagnetic induction metal detector to detect metal. All non-ferrous metals, Telescopic conveyor including iron and has high detection sensitivity. Ferromagnetic metals into the detection zone detection area will affect the distribution of the magnetic field lines, thereby affecting the fixed range roller conveyorof flux. Non-ferromagnetic metals into the detection area will generate eddy current effects, also make the detection of changes in the regional distribution of the magnetic field
