Pulse Induction Metal Detector Circuit element14 Sensors

28/10/2017 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. As these induced magnetic fields fluctuate, they also induce current in the originating inductor (antenna).

Pirate PI Schematic Pulse Induction Metal Detectors

The metal detector circuit consists of two main components: transmitting and receiving . The transmitting node consists of a pulse generator on a KR1006V1 chip (an analog of NE555) and a powerful key on a KP505A field-effect transistor (an analog of IRF740, IRF840). You can put a reverse-conduction bipolar transistor with a voltage K-E of at least 200V. It can be taken from an energy

Metal Detector using a 2 Pulse Induction Coil

In a PI metal detector, the magnetic fields from target objects add their "echo" to the reflected pulse, making it last a fraction longer than it would without them. A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take

Pulse Induction Metal Detector With GreenPAK : 5 Steps

23/03/2017 A pulse induction (PI) metal detector can be very easily implemented with a single GreenPAK configurable mixed-signal IC . Pulse induction designs have the advantage of tolerance to ground effects, and work even when submerged in water. It also performs well on non-ferrous metals.

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. PI outperforms the VLF/TR in areas where little trash is

Arduino Based Pulse Induction Detector Flip Coil : 5

Looking at the voltage of the coil in a PI detector, the resulting curve can be devided in two different stages. The first stage is the pulse itself powering the coil and building up the magnetic field (1). The second stage the is voltage decay curve, starting with a voltage peak, then ajusting fast to the "no-power" voltage of the coil (2). The problem is, that the coil changes its polarity
