The search coils is a vital part of your metal detector. It is the flat, typically circular disk, which generates a magnetic field and senses metallic targets.
The great advantage of this metal detector is the ease of manufacture of the sensor. In the simplest case, it consists of 27 turns of wire with a diameter of 0.6-0.8 mm wound in a pile on a mandrel with a diameter of 21 cm. For this MD is very well suitable coil “basket” from …
You can assemble your first pulse metal detector and, here, it came to manufacturing a search mono coil. And if you have some financial difficulties, You faced a difficult task – to make the coil yourself from the cheapest possible materials. The easiest way for self-production seemed to me such a structure: we take a …
Caluclate the parameters of Pulse Induction metal detectors Multi-turn loop of wire for metal detectors can be represented as a multi-layer air core coil with a square cross-section of winding. This coil belongs to the “Short coil class”. Wheeler’s simple formula is not suitable for calculating such a coil, as we noted in the article …
The search coil is a vital part of your metal detector. It is the flat, typically circular disk, which generates a magnetic field and senses metallic targets in the surrounding environment. It is located at the end of the stem and is connected to the control housing via a cable normally wound around the stem. …
