Walk Through Metal Detectors

Walk through metal detectors typically use pulse induction (PI) technology. The PI systems send powerful, short bursts (pulses) of current through the coil of wire. Each pulse generates a short magnetic field. When a piece of metal passes through the magnetic field, a reflected magnetic field is created. This magnetic field then reacts with the receiver coil, which, in turn, triggers the alarm system.  This initiating spike lasts a few microseconds (millionths of a second) and causes a current to run through the coil. This subsequent current is called the reflected pulse and lasts only about 30 microseconds.


A typical PI-based metal detector sends about 100 pulses per second, but the number can vary based on the manufacturer and model, ranging from about 25 pulses per second to over 1,000.


The walk-through metal detectors create large magnetic fields that cover all of the space inside the rectangular arch of the metal detector. If a person walks through the metal detector and sets off the alarm, airport security is informed that this person could potentially be hiding a dangerous, metal-based weapon, such as a knife or a gun, and further research is conducted.


The latest metal detectors have multiple zones that not only sound an alarm but also can tell the security person where the metal object is located.

The multi-zone walk through metal detectors contain multiple coils that create the separate detection zone. They can detect multiple objects, and display all the areas where they can be found. Systems are available with up to 33 zones. There are alarm lights on the side of the unit making it much easier for the security person to find the object.  To learn more, take a look at our video about “How Walk through Metal Detectors Work.”

Walk Through Metal Detectors are Safe and Effective

The Health Physics Society wrote a fact sheet on airport security that said, “Even though magnetic fields [created by metal detectors] are a form of radiation, the radiation the machine emits is nonionizing … [and] does not cause biological damage. Therefore, even repeated exposure to metal detectors has no associated radiation risk.” With this in mind, airport metal detectors provide a very effective and safe method of enforcing security in airports, schools, and businesses.


Walk through metal detectors are based on pulse induction (PI) technology. PI systems use a coil of wire on one side of the arch as the transmitter and receiver. This technology sends powerful, short bursts (pulses) of current through the coil of wire. Each pulse generates a brief magnetic field.

The detection region:
According to the basic structure of the human body detector gate is divided into eight overlapping detection area, the use of mesh detection and single frequency excitation technique to eliminate the weak areas and blind spots in the detection area, sensitivity higher, more stable performance.
Sound and light alarm, pitch speed can distinguish between metal object size,the alarm volume mode is suitable for different choice, by super bright LED alarm lamp can accurately display the body corresponding highly hiding prohibited items.
Waterproof design:
Can be in the open air (the rain) to work properly, and do not need to cover
Regional Sensitivity:
The maximum sensitivity can detect the metal content of the clip size of the object, in self-regulation between 0-255 sensitivity detection requirements to adjust the various bit
Transferred to an appropriate sensitivity, while also adjust the overall sensitivity. Pre-set metal objects weight, volume, size, location, and remove keys, jewelry, belt buckles and other false alarms.
Product Process:
PVC synthetic materials and special process, waterproof luxurious appearance is more suitable for large-scale high places.
Smart Statistics:
Intelligent traffic and alarm counting function, can automatically statisticians by the number and the number of alarm.
Anti-interference ability:
Digital, analog, and left and right balanced technology to prevent false alarms and false negatives, and greatly improve the anti-jamming capability.
Safety protection:
Double password protection, allowing only authorized personnel operation, the password needed to be modified and lost password recovery settings, and more secure. Parameter settings are automatically stored without un-interruptible power supply protection, safer and more convenient.
