Airport Metal Detectors – Best Suited Screening Method Available At The Airport
To keep travelers safe, airports use different kinds of screening equipment. Metal detectors are one such piece of equipment. Metal detectors emit low levels of radiation. Hidden weapons and other hazards that are not safe for airline travel can easily be detected by using a metal detector.
How Does An Airport Metal Detector Work?
Most of the airport and food metal detectors are based on the pulse induction (PI) method. This method uses a coil of wire on one side of the arch, which acts as the transmitter and receiver. It sends pulses of current through the coil of wire. Each and every pulse creates a magnetic field.
At the end of the pulse, the magnetic field reverses polarity and collapses, resulting in a sharp electrical spike. After the spike, another current is run through the coil. One more pulse is sent, and the method repeats. When a metal object is passed, an opposite magnetic field is created. When the pulse completely disappears, it means that metal is detected.
Advantages Of Using A Metal Detector At The Airport
Metal detectors are used in various places to screen persons or objects, like waterproof metal detectors. Its highest advantage is found in its usage at an airport. Airport metal detectors can prevent incoming weapons and sharp objects from any country. It ensures the safety of people on site. Airport metal detectors give people entry and exit process agility. They are also used to avoid embarrassment.
Types Of Screening Made By An Airport Metal Detector
Unlike metal detectors for beginners, these are used at various places in an airport. Hold baggage screening, passenger pre-board screening, cabin baggage screening, cargo screening, non-passenger screening are all carried out by using a metal detector at the airport.
Conclusion
A metal detector is now used in hospitals, schools, international organizations, airports, and various other institutions. They ensure maximum security and efficiency in all places. They are safe to be used for kids and pregnant ladies.
