Metal detector circuit diagram,The metal detector is a relatively simple device, an electronic circuit that provides good sensitivity and stability. A distinctive feature of this device is the low operating frequency. Metal detector coil operates at a frequency of 3 kHz.
Nov 10, 2009· Metal detector circuit diagrams and projects. Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced.
Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.
