Operating Principle
Portable door-type security metal detection gates use electromagnetic fields to detect metal objects. The basic steps are:
-
Electromagnetic Field Generation: The detector generates an electromagnetic field through signals emitted from its antennas.
-
Metal Object Interaction: Metal objects absorb some energy from the electromagnetic field, causing a change in the person carrying the metal.
-
Detection: The detector senses changes in the electromagnetic field and processes this information.
-
Alert: Upon detecting metal, the detector provides a visual and audible alert.
