What is walk through metal detector?

A walkthrough metal detector is a security device used to detect metallic objects and contraband carried by individuals in areas such as airports, stadiums, and government buildings.

It is made of a rectangular frame with multiple panels that emit and detect electromagnetic fields. When a person walks through the metal detector, the electromagnetic fields are disturbed if they are carrying metallic items like keys, coins, or weapons. This disturbance triggers an alarm, informing security personnel of the presence of metal objects on the person. Walkthrough metal detectors are an essential tool for maintaining security and ensuring the safety of public spaces.

Types of walk through metal detectors

There are several types of walk-through metal detectors commonly used for security purposes. Here are a few common tyepes: 
1. Single-Zone Metal Detectors: These detectors have one detection zone and are suitable for basic metal detection needs. They can detect metal objects as people walk through the detector.

2. Multi-Zone Metal Detectors: These detectors have multiple detection zones, typically ranging from 6 to 33 zones. They provide more precise metal detection by indicating the location of the detected metal through different zones on the detector panels.

3. Hand-Held Metal Detectors: Hand-held metal detectors are portable devices used by security personnel to scan individuals manually. They are commonly used in conjunction with walk-through metal detectors for secondary screenings.


4. Portable Metal Detectors: These detectors are similar to walk-through metal detectors but are designed for temporary use or to be easily moved. They are often used in situations where permanent deployment is not required.

5. Multi-Sensor Metal Detectors: These detectors utilize multiple detection techniques like metal detection, X-ray imaging, and fingerprint scanning to enhance security and identify potential threats more accurately. 

1.2 Installation of walk through metal detectors

1. Open the package and take out the door panel, control box, power cable and user manual and other accessories.

2. How much does a walk through metal detector cost?

Walk through metal detector prices can range from a few hundred to several thousand dollars. Factors such as the features, sensitivity, and customization options can all influence the final cost. For an accurate quote, please contact us right now!

3. Do walk-through metal detectors detect aluminum?

Yes, security gates are capable of detecting a variety of metal products, including aluminum blocks, aluminum sheets and aluminum products.

4. What do walk through metal detectors detect?

 Walk-through metal detectors are primarily designed to detect various metal items carried by individuals. Specifically, they can detect:
1. Electronic products such as chips, memory devices, circuit boards, hard drives, mobile phones, MP3 players, translators, recording devices, and other electronic devices. 
2. Metal items including steel pipes, cutting tools, firearms, lighters, and various other metallic objects
3. Precious metals, such as gold and silver jewelry. 
3. Other metal objects such as wires, cables, electrical appliances, electroplated items, die-cast parts, plumbing supplies, and precious metals like copper and aluminum, 
4.Other everyday items like watches, hardware products, keys, eye glass and embroidery needles.

5. Are walk through metal detectors safe?

Yes, walk-through metal detectors are safe when used in accordance with standard operating procedures.  

Before explaining why they are safe, we can first understand how walk through metal detectors work. Their working principle is based on electromagnetic induction: when current passes through the coil, a magnetic field is generated. If a metal object passes through this magnetic field, a magnetic field will also be generated inside the metal object, causing a change in the original magnetic field. The security door has a built-in high-sensitivity detector that can detect such small changes and prompt the operator through an audible and visual alarm system.

So is this electromagnetic field harmful to the human body? the answer is negative. First of all, because the intensity of the magnetic field it generates is extremely small, far lower than the electromagnetic radiation level of household appliances such as mobile phones and televisions. Organizations such as the International Council for Electromagnetic Radiation Protection (ICNIRP) and the World Health Organization (WHO) have pointed out that the impact of low-intensity magnetic fields on the human body is negligible.

Secondly, the magnetic field generated by the security gate is instantaneous. The time that people pass through the walk through metal detector is very short, usually no more than a few seconds, so the magnetic field they are exposed to is extremely short. Even under abnormal circumstances, such as the walk through metal detectors malfunctioning and working continuously, the electromagnetic field it generates is not enough to cause long-term adverse effects on the human body.

6. Can a pregnant woman walk through metal detectors?

Macrosafe walk throught metal detector has low power and produces very little electrical radiation, which is smaller than the radiation from commonly used mobile phones and computers, so it has no adverse effects on pregnant women and fetuses.
If there are specific concerns about walking through a metal detector, alternative security screening options may be available and should be discussed with security personnel.
