We all have seen metal detectors at airports, railway stations, etc., but have ever thought for what purpose it’s used? The reason for implementing a walkthrough magnetometer is to protect the public from attacks like a bomb blast. In past, many incidents have taken place in these public places, which impacted the overall reputation of a security department. Taking about hijacks of aircraft are mostly practiced until the innovation of metal detectors are introduced in departments of aviation.
Metal detectors use a coil plantation technology, which helps the device to scan the metal objects with the help of a sensor inside under the ground near the machine. If a person carrying any metal objects and walk through the magnetometer, the device immediately starts beeping. This helps the security staff to manage the public security. Apart from that, many high configured metal detectors have scanner features in them, which shows the x-ray images in a computer machine.
Apart from walking through metal detectors, there are metal detectors used manually by the security staff of an individual security department. These metal detectors are similar to step through the magnetometer, but the differentiating part is they are easy to use and convenient. These detectors are small in size and consist of the same implantation of the method the other walk through metal detectors has. These hand detectors can easily detect a person carrying any objects which are similar to iron. It uses the same technology of coil and two wires, which are used among any metal detectors around the world.
Hard to bypass
In the past, it’s easy for a terrorist to carry weapons with them to public places like the airports. But as the world has changed, it’s now tough for any of these criminals to do so. The reason is to walk through a magnetometer is hard to bypass because these machines are highly configured and specially designed to stop these kinds of criminal attacks. The machine’s implants of scanners and sensors monitor the overall body of a person and notify the security staff. If any person carrying any weapon-like objects and walks through these machines, the device will immediately alert the staff about the activity. It’s not wrong to say that these machines have reduced the crime, especially like the activities of aircraft hijacks, bomb blasts, etc.
It’s easy to understand the operation of walkthrough magnetometers, and these machines have physic-based implantation of science. They have an inserted coil in the ground attached to the device, giving the signals back with the help of the receiver and transmitter. Whenever the devices detect the objects of iron, the coils immediately come in contact with the receiver and send the signal to the transmitter. The machines start beeping loudly and alert the working staff about the threat. New technology implantation has also introduced a new feature in these machines in which a person cannot pass through if they get detected with any criminal activity. The device will make the stuck in between the security and helps the staff to control the situation.
