This walkthrough metal detector operates on electromagnetic, magnetic pulse
technologies. Electronic components will sample or process the current the receptor receives.
Metal objects are detected when the signal exceeds the alarm threshold. This kind of
walkthrough metal detector is a multi-channel metal detector with 24 overlapping detection
zones. Each detection zone produces a pulsed magnetic field.
When different shapes of metal objects from different directions pass through the
detector, the differences in sensitivity are reduced due to the overlapping structures. Each zone
has significant differences in order to detect metal objects at different heights. Advanced
microprocessor technology is used for digital signal processing and internal control. This enables
reliable metal detection capabilities, comprehensive features, as well as a user-friendly operation.

ITE PREPARATION
When determining the installation site for the WTMD, several important factors need to
be considered to ensure the best-operating conditions and security checkpoint for the maximum
flow of people.
It is essential to minimize any effects on the operation of the WTMD produced by different
interference sources.
