  • Metal Detectors Have Significant Effects
    Oct 09, 2018

    Today many devices play very important roles in different fields, such as security gates for airports and many metal detectors which not only appear at the airport but also in industrial applications. The effect of the device is remarkable as a precision detecting device for eliminating metal foreign matter contamination.

    Metal detectors are used to detect metal foreign matter mixed in the production process of food, medicine, cosmetics, textiles, etc. 

    The principle is to use a central transmitting coil and two equal receiving coils, which are mounted in a probe. Metal detectors, when the magnetic field is free from external interference, the voltage output signals they generate cancel each other out, and there is no interference.
