What are the security inspection devices that we can often contact in our lives? Fang Ji infinite tells you that the x-ray security inspection equipment that we often come into contact with in our daily life includes security gates, X-ray security inspection machines, and handheld metal detectors.

　　The "fire eye gold eye" of the security inspection machine is completely realized by X-ray, which is an electronic device that sends checked baggage into the X-ray inspection channel through a conveyor belt to complete the inspection. When luggage enters the X-ray inspection channel, it will block the parcel detection sensor. The detection signal is sent to the system control section to generate an x-ray trigger signal that triggers the x-ray source to emit an x-ray beam. The fan-shaped x-ray beam passing through the collimator passes through the object to be inspected on the conveyor belt. The x-ray is absorbed by the object to be inspected and finally bombards the dual-energy semiconductor detector installed in the channel. The detector converts x-rays into signals. These weak signals are amplified and sent to the signal processing cabinet for further processing.
 
     Handheld metal detector is designed to detect metal objects carried by people or objects. It can detect weapons, explosives or small metal objects carried in packages, luggage, letters, fabrics, etc. carried by people. The special appearance of its sensitive surface makes the operation simple and easy. It is superior to the ring sensor type manual probe. Ultra-high sensitivity, special applications such as prisons, chip factories, archaeological research, hospitals, etc.

       Security door is a detection device for detecting whether a person carries metal objects, also known as metal detection door. Metal detection safety gates are mainly used in crowded public places such as airports, stations, and large conferences to check hidden metal objects such as guns and control knives. A small number of high-end security gates on the market can immediately alarm when the metal carried by the person passing the security gate exceeds the preset parameter value according to the weight, quantity or shape, and display the location of the metal that caused the alarm, so that the security inspector can find people in time Carrying metal objects. Most factory-specific security inspection doors only identify whether metal objects are carried, located, and alarmed to prevent products from being taken out of the factory illegally. The best-performing security door can detect paper clip-sized items.
