Pulse Induction Metal Detector Circuit | element14 | Sensors

Pulse induction metal detection relies on the fact that when metal is in a changing magnetic field, eddy currents are induced in the metal. These eddy currents form complete circuits which are equivalent to electro-magnets which generate their own magnetic fields.

Gary's Pulse Induction Metal Detector - CHEMELEC

This is true for all pulse induction metal detectors. Because of the low conductivity, the eddy currents have disipated by the time the pulse delay has ended and you begin to sample the signal. The lower the conductivity of the metal, the faster the eddy currents disipate.

Metal Detectors - Theory and Practice - VLF, PI and BFO ...

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.
