Industrial Electromagnetic Metal Detector radiates an electromagnetic signal having a single operating frequency in the range of 50 kHz to 2 MHz and work by generating a low intensity magnetic field from a current flowing through a coil of wire. The Metal Detector is used by hobbyists and collectors to search for buried or otherwise hidden metal objects of value or particular interest, such as coins, jewellery and artefacts of historical significance. The Metal Detector can examine the various types of distortions produced in the magnetic field by a surrounding matrix of materials. Industrial Electromagnetic Metal Detector is equipped with sensing coil and sensing circuit that are used to detect presence of a metal object in the zone by comparing perturbations in the magnetic field caused by the presence of the metal object to a threshold value.
