Schematic Pulse Induction Metal Detector Circuit

The theory behind how a basic pi metal detector works is examined along with the basic details of a readily available design for a detector.

Schematic pulse induction metal detector circuit.

A pulse induction pi metal detector can be very easily implemented with a single greenpak configurable mixed signal ic cmic. White s surfmaster pi pulse induction metal detector schematic diagram. Schematic diagram of white s surfmaster pi metal detector a good quality simple pi pulse induction design with an affordable price. The coil transmits a pulse toward the ground generating an answering pulse from the target object.

Pulse induction metal detector part 1 pdf metal. Available schematic for a pulse induction pi metal detector. Heathkit groundtrack gr 1290 vlf metal detector circuit diagram and detector coil construction notes. Pulse induction pi metal detectors are sending repeated pulses of electrical current to the search coil producing a magnetic field.

A sampling circuit measures the pulse and sends it to an integrator which generates an audio tone. Pulse induction designs have the advantage of tolerance to ground effects and work even when submerged in water. Detects all metallic objects with unbelievable depth and sensitivity on the hardest to hunt black sand beaches and in wet salt. Pulse induction metal detector part 2 pdf metal.
