A walk-through metal detector is a security screening device designed to detect metallic objects on a person passing through it. These detectors are commonly used at airports, courthouses, stadiums, and other high-security locations.
Description & Functionality
1. Structure:
Typically consists of a tall, rectangular archway with two vertical panels housing the detection sensors.
A control panel or display screen is usually mounted on the side for monitoring and adjustments.
2. Detection Mechanism:
Uses electromagnetic fields to detect metal objects.
When a person walks through, the detector scans for metallic items, triggering an alarm if any are found.
3. Sensitivity Settings:
Can be adjusted to detect small or large metal objects, depending on security requirements.
