Арочные металлодетекторы
В сфере безопасности, для досмотра, выявления предметов приборы, реагирующие на металл, применяются давно. Созданы модификации с расширенным набором базовых и дополнительных функций.
Пример такого устройства — арочный металлодетектор. Он усовершенствованный под специфические условия объектов, на которых используется.
Описание, принципы работы
Описание, принципы работы арочных металлодетекторов
Арочные металлодетекторы — стационарные устройства (сборные или готовые), обнаруживающие металлические предметы, проносимые сквозь них.
Они выполнены аркой (рамкой) и способны сканировать человека или габаритные объекты полностью. Они также бнаруживают сплавы в диэлектрических и слабопроводимых веществах (дерево, пластик, одежда).
Работа устройства основывается на применении радиоволн. Одна стенка посылает специально сгенерированный радиосигнал к другой, которая его принимает и направляет обратно. Материалы обладают сопротивляемостью электромагнитным и радиоволнам, поэтому сигнал, проходя сквозь них, теряет силу или вовсе не проходит.
Встречаясь с предметом на теле человека, двигающегося сквозь рамку детектора, радиоволны отражаются от него и возвращаются быстрее, чем другие сигналы. Устройство фиксирует время отражения, если скорость отражения свидетельствует о металлической преграде — срабатывает световая и звуковая сигнализация.

Arched (walk-through) metal detectors
In the sphere of security the devices reacting to metal have long been utilized for the purposes of identification and control. New modifications with an expanded set of basic and advanced features are being constantly created in order to ensure the safety of the people using them.
The outstanding example of such a device is an arched (walk-through) metal detector. It is considerably advanced to fit into the specific conditions of the facilities in which it is used.
Description, the principles of operation
Description, the principles of operation of arched (walk-through) metal detectors
Arched (walk-through) metal detectors are the fixed devices (prefabricated or finished), capable of detecting the metal objects carried through them. They are made in the form of an arch (frame) and equipped with the ability to perform a full scanning of a human body or any other dimensional object of a similar size. What is more, the detectors have the capacity to identify the alloys in various dielectric and low conductive materials (i.e. wood, plastic, clothing, etc.), thus significantly improving the security level.
The operation of the appliance is based on the utilization of radio waves. One of the walls sends a specially generated radio signal to the other, which receives and sends it back, therefore providing a continuous process of the wave reflection. The materials having a high resistance to electromagnetic and radio waves partially or completely interrupt the passage, so the signal going through them either loses its strength or does not pass at all.
On identifying the resistant subject on the human body moving through the detector frame, the radio waves are reflected from it notably faster than other signals. The device immediately captures the reflection period and consequently, if the rate of it indicates a metal barrier, the system activates light and sound alarm.
