Walk through metal detector manufacturers take you to understand what is the photoelectric linkage and flying object detection of security gates
2022/08/03
The walk through metal detector manufacturer tells you that the detection uniformity of the security inspection door refers to the ability of the security inspection door to maintain uniform sensitivity in the entire detection area regardless of the shape and direction of the metal object. Detection uniformity directly affects the identification ability of the security gate.
The photoelectric linkage of the security gate: the sensor on both sides of the door senses the passage of people. The walk through metal detector manufacturer tells you that when a person carries metal through the security gate, the security gate will issue an alarm prompt, otherwise the security gate will not alarm.
Flying object detection of the security gate: When the sensor disconnects the linkage with the security gate, the security gate enters the signal collection state. When metal passes through the security gate, the security gate will immediately issue an alarm prompt.
The walk through metal detector manufacturer tells you that the sensitivity of the security gate is usually set according to the weakest position of the detection area. If the detection uniformity is poor, it may cause other detection areas in the channel to be too sensitive, resulting in significantly reduced discrimination. Walk through metal detector manufacturers tell you that when testing the uniformity of detection of security gates, you should always use physical objects, such as coins, weapons, or simulated weapons. Using a cylinder or sphere as the test object may give a false indication of the true detection uniformity of the security gate.
