Pulse Induction Metal Detector Coil Design

Pulse induction metal detectors use one coil as both the transmitter and the receiver.

Pulse induction metal detector coil design. The system consists. I have reade a guide for making a pi metall detector pulse induction metal detector with dsp. Although they differ in the way the signals are processed the electronics which generate the magnetic field pulses is almost always identical. A typical pulse induction detector sends about 100 pulses a second.

The main part to generate magnetic pulses is the coil. The search coil was demonstrated by using the wire with the diameter of 0 3 mm 0 5 mm and 1 0 mm and the dielectric plate with the 30 cm 30 cm and 35 cm 35 cm the time constant and the currents of the coil as the variation of the coil size and the number of coil turns was characterized. There are many projects floating around on the internet regarding pulse induction metal detectors. It sends pulses of electricity into the ground that generates a magnetic field.

I am interested in making one but i have some quesion about the coil and the ground penetration. When the pulses hit a metal object the field is reversed and the detector picks up that signal. The aquapulse is designed for deep diving and can withstand 100 meters of pressure. This paper presents the pulse induction metal detector using sample and hold method.

The proposed method is to measure output voltage from search coil. Aquascan aquapulse aq1b diver metal detector review. The aquascan aquapulse is a top notch piece of kit and many consider it the best pulse induction metal detector for divers.
