Principles Of Metal Detectors

Produced by Crystal 3.5-4.95M of sinusoidal oscillations, crossover frequency 7.8K sine wave, transistor power amplifier with the coil after the door panel (7) coil electrical

Magnetic wave emission from 1-6 district receiving coil separately. After receiving compares the received signal and the reference signal and found changes, change capture card output level, CPU 300 milliseconds to scan the 6 regional acquisition card data, determine the location where the metal and the output displayed.
