Electronic metal detector | Metal detector, Detector, Free ...

Nov 6, 2018 - The metal detector is a relatively simple device, an electronic circuit which provides good sensitivity and stability. A distinctive feature of such devices is its low operating frequency. The inductance coil of the metal detector work at a frequency of 3 kHz. This ensures, on the one hand, weak reaction to unwanted signals (e.g., signals generated in the presence …

When a ferrous or magnetic object is brought near the search coils the phase of the received signal is advanced with respect to the transmit signal. The oppo-site occurs when a non-magnetic conductor is brought near the search coils. Thus, this type of detector can effectively 'discriminate' between fer-rous and non-ferrous metals as well as exclude ground effects — …
