- The electromagnetic field radiates upwards, encompassing those who pass by the detector.
2. Metal Interactions:
- When someone walks past the detector, the electromagnetic field is in contact with any metal object they carry.
- This causes the secondary magnetic field to the metallic objects, which contrasts with the primary electromagnetic field created by the device.
3. Alarm Triggering:
- The detector has an RF receiver coil that can detect fluctuations that occur in electromagnetic fields. If metal objects interfere with the area, it triggers changes in the signal received.
- These fluctuations are closely monitored. When they are over set thresholds, the detector sets off an alarm.
4. Types of Alarms:
- Airport metal detectors are developed to identify different kinds and types of objects made from metal. It is possible to program them with various alarms to various kinds of metal or other compositions.
- Standard alarms are visually-based indicators, audible alarms, and alerts an alert to personnel in charge of security.
5. Sensitivity Adjustments:
- They can be adjusted to ensure that detectors aren’t susceptible or create false alarms in the case of small, non-threatening objects such as coins or jewelry.
- Security personnel can adjust the sensitivity settings according to the airport’s security level and specific policies.
6. Dual-Technology Scanners:
- Metal detectors in modern airports include electromagnetic fields and other technologies, like millimeter-wave scanning or backscatter X-ray imaging.
- These scanners with dual technology provide a more thorough assessment of the passengers and help to detect metal and non-metallic dangers.
7. Conformity with the Regulations:
- Metal detectors at airports must conform with international regulations and standards to comply with strict performance standards.
- Maintenance and regular calibration is crucial to ensure their accuracy.
Aluminum Foil and Metal Detectors
