What is walkthrough metal detector?
Walk-through metal detectors utilize magnetic fields to detect metal that passes through them. The science behind how they work is based on Maxwell’s equations. The latest detectors include multiple detection zones allowing them to pinpoint the location of the metal causing the alarm.
Where are walk through metal detectors used?
Walk-through metal detectors (WTMDs), also called portal or personnel screening metal detectors, are devices used to screen individuals for weapons or other concealed contraband. They are used for security at checkpoints in airports, government facilities, entertainment and transportation venues, and other buildings.
Do walk through metal detectors detect aluminum?
Metals such as iron, nickel and cobalt are detected by passive and active metal detectors. Other metals, such as copper, brass and aluminum, are detected only by active means. Walk-through metal detectors are categorized as single-zone or multiple-zone.
What is the principle of metal detector?
The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground.

What is the hobby of metal detecting called?
I also learned from Western & Eastern Treasures that people who metal detect are called “metal detectorists.” It was gratifying we had our own “ist” like numismatists, philatelists, or contortionists.
Who invented the metal detector in 1881?
Alexander Graham Bell
In 1881, Alexander Graham Bell invented the first metal detector. As President James Garfield lay dying of an assassin’s bullet, Bell hurriedly invented a crude metal detector in an unsuccessful attempt to locate the fatal slug.
Which sensor is used in metal detector?
Detecting metal only Inductive proximity sensors can only detect metal targets. They do not detect non-metal targets such as plastic, wood, paper, and ceramic. Unlike photoelectric sensors, this allows a inductive proximity sensors to detect a metal object through opaque plastic.
What happens if you walk through a metal detector?
If a person walks through the metal detector and sets off the alarm, airport security is informed that this person could potentially be hiding a dangerous, metal-based weapon, such as a knife or a gun, and further research is conducted.
How are metal detectors part of a security system?
They are part of a total security system that includes cameras, door access control, and emergency paging systems. Metal detectors are effective and safe. Just like IP cameras and door access control, they add to your safety and security. Here’s how they work.
Where do they make Metor Metal detectors in Finland?
In Espoo, Finland, Rapiscan Systems designs and manufactures its Metor Metal Detectors, used in people-screening applications.
Where does Rapiscan make the metal detectors they use?
The primary centre for development and distribution of X-ray systems for hold-baggage screening is also at Salfords. In Espoo, Finland, Rapiscan Systems designs and manufactures its Metor Metal Detectors, used in people-screening applications.
