How Do Door Frame Metal Detectors Work?

Posted by Admin on March, 09, 2023

The main purpose of a doorframe metal detector is to detect metal objects hidden inside. Door frame metal detectors play a crucial role in enhancing security at airports, railway stations, and other public areas. Door frame metal detectors are used to detect concealed weapons on the human body and prevent acts of violence, terrorism, crime, etc.

Door frame metal detectors are also called walk-through metal detectors. These are installed at the entrances. These door frame metal detectors work on the electromagnetic principle, which involves the use of electromagnetic fields to detect metallic objects on the human body.

Door frame metal detectors typically use two types of electromagnetic fields: one is pulse induction, and the other is low-frequency oscillation. Pulse induction door frame metal detectors create a short magnetic field when a metal passes through this field, triggers an alarm. A low-frequency oscillation metal detector uses two coils to generate an electromagnetic field and interact with metal objects.

The sensitivity of a DFMD can be adjusted to detect particular metal objects like weapons, bombs, guns, etc. Door frame metal detectors are efficiently used in preventing weapons, bombs, etc. from entering security areas.
