Installing a 100% Accurate Metal Detection System
Metal detection systems are one of the security solutions widely used in many fields from aviation, commerce to politics. With the ability to accurately identify metals, these devices help ensure security and prevent potentially dangerous situations. To learn more about the structure and operating principles of this metal detection system, please follow SECOM’s article below.
Overview of metal detection systems
Metal detection systems include devices and tools designed to detect and identify metals from the surrounding environment. Specifically, metal detectors and magnetic metal detector gates are two typical representatives of the system. These products are of interest to many businesses operating in the field of security monitoring because of their ability to ensure and enhance security and safety in quality monitoring.
What is a metal detector?
Metal detectors are one of the devices used in many areas of life. Thanks to its high applicability and convenience of use, this product line has received many positive feedback from customers.
Concept
Also known as a metal detector, a metal detector is a specialized device for detecting objects containing metal. This product allows users to easily find metals in the surrounding environment that cannot be seen with the naked eye.
Structure
Metal detectors operate on the principle of electromagnetic induction, so the structure of this device includes:
- Stabilizer: Make sure the detector disc is always in a stable position when scanning metal containers.
- Machine control panel: Contains important components such as control circuits, batteries, speakers and processors.
- Connecting rod: Helps link the control panel to the search coil.
- Metal detection coil: Another name is a probe with the function of detecting and sensing the presence of metal.
- Sound system: Activates an audible alarm when the detector detects the existence of metal in an object. For modern metal detectors, this part is often designed with a display screen to help users determine the exact location of the metal.
Principle of operation
When the machine is started and the probe is brought to the area to be tested, the probe will create a magnetic field with uniform magnetic field lines. In case the probe collides with metal objects, the magnetic field lines will change. The machine will detect this change and send an alarm signal.
Accordingly, the variation of magnetic field lines will depend on the distance and size of the metal object. If the metal is nearby or large in size, the alarm signal will be larger and clearer.
Currently, high-end metal detectors apply more complex principles to help bring higher sensitivity. In particular, some advanced detectors have the ability to take images and accurately determine the location of metal deep underground, helping users quickly locate the target in the most accurate way.
What is a metal detector gate?
Metal detector gates are devices that often appear in areas such as airports, office buildings, shopping centers, places where large events are held, etc. With high sensitivity, this product is used to Protect safety and prevent theft in public places.
Concept
A metal detector gate is a security system that uses electromagnetic induction technology, creating a magnetic field around two doors to detect changes in the magnetic field when a conductive metal object passes through. Currently, there are types of detector gates designed such as high sensitivity detector gates to prevent theft of belongings, lower sensitivity detector gates suitable for detecting large metals such as weapons, detector gates with Fixed or mobile detectors, detectors for indoor or outdoor use,…
Structure
Currently, there are many different types of metal detectors on the market. However, in terms of structure, they all have two main parts: the controller and the technical box.
- Detection gate controller: This is considered the main part of the gate with the main task of receiving and processing information from the technical box, thereby analyzing and determining the existence of metal, then reporting. for users. The controller of the metal detector gate is basically programmed and the programming mode can be changed according to the user’s needs. When adjusting programming mode, the controller will also make changes to match the sensor area. Normally, the controller is adjusted to operate at the most sensitive level, helping to promptly detect the appearance of metal objects.
- Technical box of the metal detector gate: Where many sensors are concentrated, the function of the technical box is to detect and analyze metal objects. Information after being collected from the sensors will be sent to the controller for processing. For modern detector product lines, technical boxes are often integrated with smart features such as control keys, password security mode and remote automatic control capabilities.
Principle of operation
Similar to the metal detector device, the operating principle of the detector gate also uses electromagnetic induction and transceiver coil but is integrated with more advanced and complex technology.
Metal detectors often use pulse induction (PI) technology to generate strong and short current pulses through the coil. Each pulse creates a short magnetic field, and when a metal object passes through the magnetic field, it creates a reflected magnetic field. The receiver coil detects a change and activates the alarm system. This sudden change will take place within a few microseconds, creating an electric current flowing through the coil called a reflected pulse. Metal detectors based on PI technology typically send out around 100 pulses per second, however this number can vary depending on the manufacturer and model.
The metal detector gate creates a large magnetic field, covering the space inside the detector’s rectangular dome. If a person passes through the detector gate and the alarm system sounds, security staff will be notified that this person is likely hiding a dangerous metal object such as a knife or gun, thereby taking control measures. check more closely.
Why should you install a metal detection system?
Currently, metal detection systems are widely used thanks to the important benefits that these devices bring. The system helps detect and promptly prevent crimes and affect regional security related to the transportation and storage of weapons and dangerous metal materials such as knives, guns, etc. .
Especially in crowded places such as airports, event venues, supermarkets, metal detection systems will contribute to enhancing security, ensuring a safe and secure environment for the community. Besides, using this security solution also helps prevent property loss, protect the lives and rights of organizations and individuals. This shows the effectiveness of metal detection systems, from ensuring public security to managing corporate assets.
Are metal detectors harmful to human health?
Today, there is still mixed information about the effects of metal detectors on human health. Therefore, many people feel worried, especially individuals who are frequently exposed to metal detection systems. So are these devices safe for health?
According to many studies, these types of magnetic fields can lead to nervous system dysfunction, immune system dysfunction and a number of other health problems. However, when exposed to the magnetic field emitted by metal detectors, everyone’s health is guaranteed.
Because the amount of magnetic field from the metal detector or magnetic door is very small, it is unlikely to cause harm to human health. In addition, the metal detection system is designed and manufactured according to standards, ensuring safety when used.
Some applications of metal detection systems
With superior features, metal detectors are commonly used in many different fields, especially ensuring safety for the community, individuals and organizations. Applications of metal detection systems in security protection include:
- Airports and airports: Metal detectors are used to detect and prevent the carrying of weapons or dangerous metal materials before boarding an aircraft. This helps ensure the safety of passengers and crew during the flight.
- Border control stations: Border management units often use metal detection systems to check and control the circulation of people and goods, preventing the smuggling of weapons and dangerous materials.
- Buildings and public works: In high-rise buildings, shopping centers or other works, we often encounter metal detection systems. The main purpose of these devices is to ensure the safety of residents and visitors in the area.
In addition, metal detectors and gates are also used in events, conferences, in factories, production facilities and entertainment areas.
