Supply of the metal detector metal detector structure: metal detectors www.sh-shenyi.cn usually consists of two parts, namely a metal detector and automatically remove the device, which is a core part of the detector. Internal distribution detector three sets of coils, i.e., the central transmitting coil and receiving coils two peer to generate high frequency magnetic field through the intermediate variable transmission connected to an oscillator coil, the induced voltage on both sides of the idle state when the receiver coil Before undisturbed magnetic field cancel each other to achieve equilibrium. Once the metal impurities into the magnetic field, the magnetic field is disturbed this balance is broken, the induced voltages of the two receiving coils will not be able to offset the induced voltage is not offset by the enlargement process control system, and an alarm signal (detection of metal impurities ). The alarm system can automatically remove the device driver, so as to metallic impurities excluded from the production line.
