Walk through metal detectors are seen in airports, shopping malls and other more commercial settings. It is one of the essential security instruments used for the detection of threats.

Over the years in the past, metal detectors have come a long way and today, they are much more advanced. Available in many different forms, right from handheld to walk through, metal detectors offer reliable and accurate performance to ensure security on premises they are used.

However, have you ever given a thought about how walk through metal detectors actually work? Or how much detection performance can they deliver?

Continue to read till the end to find answers to these questions and learn all things important about walk through metal detectors.

How does walk through detector functions?

Pulse or continuous wave technology is typically used in most walk through metal detectors. To be more precise, an electricity surge passes through a coil made of copper wire.

This creates an electromagnetic field and when any metal item passes through this field, the sensors present detect magnetic field that is reflected from the metal item. The reflected magnetic field reacts with the receiver coil that causes the alarm to go off.

This entire process is where the capability range of walk through metal detectors can be seen. For example, some metal detectors can only sense detecting the ferrous metal objects whereas some detectors have the capacity to detect both ferrous and non-ferrous metal objects.

Different types of Walk Through Metal Detector

There are mainly two types of walk through metal detectors based on the level of detection. They are –

Single Zone Metal Detection

The single zone metal detection can only target and identify one place on a human body. While it may be a reliable detection process, the level of security achieved from it is limited.

Multi Zone Metal Detection

As the name itself suggests, this type of metal detector is able to target and identify in more than one place. With multiple detection occurring at the same time, you can get higher security level detection. The level accuracy is also increased when you are using multi-zone walk through metal detectors.

Common locations and applications of Walk Through Metal Detectors

In earlier times, walk through metal detectors were only seen in airports. However, today this instrument is used in commercial settings as well such as police stations, shopping malls, schools and other more locations.

Interestingly, walk through metal detectors are also used in warehouses or manufacturing facilities for preventing any loss. The scope of security that walk through metal detectors provide is pretty vast which is why they are used in different commercial facilities for ensuring utmost security.

They are ideally located at the entrance of any setting so that all the entries can be checked for preventing any security concerns. They are also placed at the exit of any facility to prevent any sort of theft.

So, what more are you waiting for? If you are looking for a way to enhance your security system then make sure to install high quality walk through metal detectors now.
