  • Metal Detectors - Theory and Practice - VLF, PI

    Metal detectors Theory and practice. Metal detectors are used in a wide range of applications from landmine detection to safety in airports, office buildings or schools. They can also be useful around the house to help locate lost coins, jewelry, keys and gas lines. Metal detectors helped archaeologists in the discovery of precious artifacts and coins that were once the everyday

    Metal Detector circuit diagram. As shown, the circuit oscillates at around 230kHz. One may also experiment with the frequency by changing the value of C1. A Faraday shield may be added to reduce ground effect and capacitive coupling, and this is wired to 0V. Metal detector video with a funny song . Since the inductor resists rapid changes voltage, the charging of C1 is slightly delayed as the

  • Understanding Sensitivity in Metal Detection

    A metal detector's ability to identify a non-spherical contaminant such as wire or swarf, is partially determined by the type of metal contaminant (ferrous, non-ferrous or stainless steel), as well as the metal object's orientation. Orientation effect is only observed when the contaminant's cross-sectional area (i.e. diameter of a wire) is less than the metal detector's spherical

  • Simple Metal Detector Circuit with Applications

    A simple metal detector circuit diagram project is designed using IC 555, as you can see in the 555 timer circuits, these circuits detect the metals and magnets. When a magnet is near to the 10mH choke, the o/p frequency changes. This circuit can be powered from a power supply, which can provide an o/p DC voltage between 6V to 12V. If metal is near to the coil L1, it produces a
