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.

This metal detector, due to the use of a quartz crystal oscillator and a difference frequency signal multiplier, makes the circuit stable and extremely sensitive. Although the circuit uses five ICs, the cost is very low (30 yuan About), its use effect is no less than a few thousand yuan of imported products.

The design of a metal detector's circuit diagram can determine how sensitive the machine is to metals of different shapes, sizes, and densities. A good design should be able to …

Enter the pulse induction metal detector circuit schematic. A pulse induction metal detector works by emitting an electrical pulse into a coil of wire, and then detecting any current reflected back from metal objects in its vicinity. This type of detector is much more sensitive than conventional metal detectors, which are limited to finding ...

If you fall into this category, consider building a Pulse Induction (PI) Metal Detector Schematic Circuit. PI metal detectors have several advantages over conventional single-frequency VLF (Very Low Frequency) metal detectors. Unlike VLF metal detectors, they don't suffer from the effects of ground mineralization.
