Metal Detector using a 2 Pulse Induction Coil

2006-10-24  The kind of metal detector we have built is based on pulse induction (PI). PI systems may use a single coil as both transmitter and receiver, or they may have two or even three coils working together. This type of metal detector sends powerful, short bursts (pulses) of current through a coil of wire. Each pulse generates a brief magnetic field.

Pulse‐induction metal detector with time‐domain

A novel pulse-induction (PI) metal detector (MD) is proposed to decrease the saturation time of the output voltage and increase the detection depth. The proposed MD utilises a receiver with a time-domain bucking circuit. The bucking circuit decreases the output voltage significantly without a target, so that the output voltage can be ...
