Pulse Induction Metal Detector
costalegre November 21, 2020, 11:12pm 4. PI (pulse induction) metal detectors use a single coil which is induced with high voltage pulses from an fet amplifier circuit usually driven by a pwm (pulse width modulation) signal, easily done with an Arduino. Back EMF pulses from the coil are sampled with a attenuator circuit and fed to a RX Op-Amp ...

The difference between PI and VLF metal detectors
Here are the differences, along with their pros and cons. VLF stands for very low frequency and PI stands for pulsed induction. VLF technology is found in most metal detectors. VLF transceiver coils measure the phase shift between the transmitted and returned frequencies. PI detectors send pulses of current through their coil (s) and …

Metal Detector Frequency Guide – MetalDetector
An example of 12 kHz frequency is when a metal detector transmits and receives 12,000 times every second. If a signal repeats itself 15 times every second, its frequency is 15 Hz. A typical metal detector's best frequency for coins jewelry and relics is between 5 kHz to 15 kHz. This is the range where you will find most metal detectors for ...

Understanding The PI Detector
The time between when the pulse quits and the sample is taken is often referred to the delay time. The delay time on most Gold Hunting PI detectors is 15 usec or less. A delay of 10 usec will show a distinct improvement, especially to very small gold in the few grain range over a detector having a delay of 15 usec.
