Pulse Induction (PI) metal detectors use a method called pulse induction to detect metals. They operate by sending short, powerful bursts of electrical current through a coil, creating a magnetic pulse. When this pulse interacts with metal objects, it induces a secondary magnetic field that the detector’s receiver coil picks up. The system measures the time it takes for the magnetic pulse to dissipate, which varies depending on the type and size of the metal. PI detectors are highly effective in highly mineralized soils and are often used in deep-sea diving, treasure hunting, and detecting metal in challenging environments.
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 …
Pirat – stands for: PI – means a pulse metal detector, and RAT – author’s site: “radioscot” . This metal detector has won the glory of a simple and inexpensive instrument, a small number of accessible, not scarce parts, with proper assembly and serviceable parts, the instrument works immediately, with almost no settings. If we …
