Working Principle Walkthrough Metal Detector

Working Principle Walkthrough Metal Detector

     Walkthrough metal detector is a kind of equipment used to detect potentially dangerous items on personnel, widely used in airports, train stations, subway stations, conference centers and other public places.

The following is a detailed description of the working principle of the walkthrough metal detector:

     1. Electromagnetic induction: When carrying metal items through the walkthrough metal detector, the electromagnetic field inside the walkthrough metal detector will interact with the metal items. Metal objects can cut magnetic fields, distorting them. This distortion is detected by sensors inside the walkthrough metal detector.

     2. Signal processing: The microprocessor inside the walkthrough metal detector will process the signal collected by the sensor. Through the analysis of magnetic field distortion, we can judge the nature of the goods carried. If it is judged to be dangerous goods, the walkthrough metal detector will issue an alarm signal.

     3. Human safety: During the detection process, the magnetic field intensity generated by the walkthrough metal detector is lower than the human safety threshold. Under normal circumstances, the human body does not feel any discomfort. At the same time, the walkthrough metal detector adopts the scanning technology of radiation safety to the human body to avoid radiation damage to the human body.

     4. Accuracy and false alarm: When the walkthrough metal detector is designed, the sensitivity and false alarm rate of the equipment will be adjusted according to the needs of different occasions. Higher sensitivity can detect smaller metal items, but increases the probability of false positives. Conversely, the sensitivity is lower and the false alarm rate is lower, but smaller dangerous items may not be detected.

     The walkthrough metal detector produced by our company has high sensitivity for metal detection, light weight, strong anti-interference and stable performance. The product is made of high strength special material, very light texture, easy to transport and install. The operation interface is intuitive and easy to use. Our walkthrough metal detector has accumulated rich application experience in the world, and has won high praise from customers. Won a good reputation. Whether it is the airport, train station, subway station or conference center and other public places, you can see our walkthrough metal detector figure. Our company has been committed to providing customers with high quality products and quality service, to maintain social security and people's life safety contribution.
