The principle of airport metal detector. Jun 29, 2020. Airport security officers use hand-held airport metal detectors to check passengers. The basic idea is that when a detector coil is close to a metal object, an electric current is generated in the metal object. If this change can be detected, it can be determined that there is a metal

BBASICS AND THEORYASICS AND THEORY Metal

Metal detectors work on the principle of transmitting a magnetic fi eld and analyzing a return signal from the target and environment. The be varied by a metal detector operator varying the controls of the metal detector. Most discriminating metal detectors also have a visual display which indicates properties of a detected metal target.

Metal Detector Sensor Basic Explanation And Applications

Metal detector 1 Metal detector 2 ∗ 1 The metal detector is best positioned at the last stage before delivery of the product to the consumer. ∗ 1 • The metal detector passline height must match the product height. Setting Up Line with Even Higher Sensitivity Detection

The Principle of Metal Separator Metal Detector Factory

2017-8-10  Non ferromagnetic metal entering the detection area will produce eddy current effects, and will also change the magnetic field distribution in the detection area. Generally, the metal separator consists of two parts, the metal separator and the automatic reject device, in which the detector

Metal Detector Discrimination Chart (How to DIY Guide)

2020-8-29  Following this same principle, it’s how the metal detector discrimination system works. Some models use graphics and others numbers to indicate to the user the kind of metal near the search coil. Usually, each model uses its own classification system. So, there’s not a universal discrimination chart that works with all metal detectors.
