Metal detector frame: adjustment, installation, instruction and feedback

The metal detector frame is veryoften - at train stations, in shops and clubs. Such devices work by creating an electromagnetic field, when in the event of the appearance of metal objects it is distorted. More advanced and reliable in the work are stationary models, which are also called arched.

What is the essence of

The metal detector is placed in the pass zone or immediatelyAfter the door, or in a special fenced area. Power is provided by an alternating current. The installation features of these devices include a flat surface that does not emit vibrations, and remoteness from any metal products. In general, the main way to protect crowded spaces is the frame-metal detector. The instruction of each model prescribes attention to a number of trifles concerning the setting and competent installation. All stationary models have a common operating principle, and the differences are expressed only in technical characteristics:

• the scale step size when adjusting the sensitivity;
• the possibility of using several detectors at once in the same network;
• the possibility of exploitation in an external environment;
• design.

Design features

A metal detector is a device thatdetermines and classifies the metal. The wire lies inside the transmission frame, and the electric current moves through it - it creates an electromagnetic field. If a metal object is near the frame, the magnetic field will begin to change, resulting in an electric current being produced. They will create a magnetic field that will move in the opposite direction to the transmitter's main field, and the metal will be detected. The outer frame-metal detector also has a coil that maximally neutralizes the effect of the transmitting coil-it is called a receiver. When choosing this equipment, it is important to take into account the quality of discrimination, that is, the detector must recognize and classify the detected objects.

How does it work

How does the frame-metal detectors work? In fact, the principle is simple: from one wall of the frame to another, a radio signal is sent, which is then returned. But radio waves can not pass through metal, so when colliding with metal products, the reflected signal will return much faster. When the reflection time of the sent signal decreases, the device immediately works.

In this scenario, the framework will respond toany metal products - from rivets on clothes to zippers on a bag. Setting the frame-metal detector reduces the sensitivity of the device, which at the same time does not affect its effectiveness. It turns out that all large objects made of metal, which will rush through the frame, will be immediately detected.

Is there any harm

Today, it is increasingly said thatmetal frame is harmful to human health. Experts say that the degree of harmfulness depends only on the principle of operation of a particular device. Most frames record changes in the magnetic field, if metal objects are inserted into it. When passing through the frame, the electromagnetic field penetrates us, but it is of low intensity. It turns out that the metal detector frame can not harm.

GARRETT Magnascanner CS-5000

It is the easiest, but at the same time effectivemetal detector manufactured in the USA. The upper part of the arch is supplemented with a control unit. You can adjust the frame to respond to any mass of metal - from a few grams to a kilogram and more. The stationary frames of metal detectors GARRETT Magnascanner CS-5000 have a number of features:

• built-in programs in the amount of 20 pieces for various installation conditions - at school or airport;
• You can change the passwords that will control the device settings;
• each frame is complemented by a range of accessories;
• each frame program is configured for 200 sensitivity levels;
• the state is constantly displayed on the display;
• the ability to customize the frame so that false positives are filtered;
• frames of this brand can be put side by side, and they will work effectively

Frame metal detector GARRETT MagnascannerCS-5000 is made in the form of an arch, the panels of which are located at a distance of 80 cm from each other. The control and display unit located above is protected from external influences. Many customers choose products of this proven brand, noting among the advantages of modern design, practicality of coating and impact resistance. At hit of metal in sight of a frame about it signals a light and sound signal.

"Search-VP"

Stationary metal detector frame "Search-VP"Easily detects firearms and large metal objects that are often hidden under clothing. The peculiarity of the model is that it can also be operated in the open air under the influence of external natural factors. The distinctive features of this frame include the following:

1. Low probability of false positives.
2. Auto-tuning after the frame has been turned on.
3. The design is folding, so the installation of metal detector frames is possible in any premises and even on the street.
4. The degree of sensitivity is adjustable.
5. Low power consumption.

"Pautina-R"

The arched metal detector has microprocessor control and is widely used when it is necessary to detect metal objects when people are being searched.

The model has a modern design andpossibility of operation in any temperature conditions. Installation of metal detectors is simple, and the equipment has a number of additional features:

• adjust the frame and control them by remote control;
• there is a built-in self-diagnostic system;
• during installation, the control unit is located in the frame or is taken out of their limits;
• the ability to synchronize several detectors that can work simultaneously.

"Web-CM1"

This metal detector frame is portable, andmobility is the main advantage that many users point out. The design itself is collapsible and consists of 7 elements. Thanks to the scheme, which is controlled by the microprocessor, a uniform and high-quality response to metal objects in the zone of the device is ensured. The advantage of the model is the ability to work on battery power. In addition, due to its low weight, it is possible to transport the device even in the trunk of a car. The capacity of the metal detector frame of this model is 40-60 people.

"Roadblock RS-800"

Stationary arched metal detector of this brandallows you to check a person and identify any metal objects. The system operates in six zones and has adjustable sensitivity, itself counts passengers and the number of alarms. The manufacturer guarantees absolute security when a person passes through the frame. Signal processing is carried out using a prospective unit, thanks to which the device operates reliably and stably in all conditions.

"Cordon C1"

This frame detects metal objects.easy, and information about detected items is displayed on the front panel thanks to a 6-zone indicator. Feature of the model - the ability to adjust the sensitivity in a wide range.

These systems are designed specifically for equipping stations, stations, stadiums, banks, schools, hospitals and any institutions where there are a lot of people. The distinctive features of this frame include:

• maximum security level;
• compliance with technical regulations and standards;
• good bandwidth;
• operation in six detection zones;
• presence on the front panel of the LED display;
• reliable penetration protection thanks to program password.

Ceia

High selectivity is the main feature,which differs this frame of the metal detector. The principle of operation of this equipment is the same as that of other analogues. Buyers say that these frames are ideal for installation where the high permeability - in hotels, museums, concert halls. The second advantage, according to customers, is an aesthetic design that fits perfectly into any interior. The system allows you to adjust the degree of sensitivity, and the installation is simple, does not require preliminary and periodic calibration.

conclusions

Modern technology opens up largeopportunities to ensure good throughput of people in various establishments and at the same time prevent emergencies. The most important thing is that all metal detectors are safe for people, which is confirmed by quality certificates. Ease of installation allows you to ensure security in any crowded room, promptly identifying illegally carried by metal objects.
