1. Exact positioning
The TX is a multi-channel metal detector with six overlapping
detection zones. The zones create a sequential sine-wave magnetic
field within the detection area of the WTMD (Walk-through Metal
With overlapping construction, sensitivity differences are
minimized when metal objects of different shape pass through the
WTMD in various orientations.The product has a unique configuration
of the transmit-receive coil. This provides double-side
transmission and double-side reception performance. Then the
equipment can position the detected object exactly and indicate the
alarm position directly.
2. Microprocessor technology
Scanning speed of the electromagnetic wave created by microcomputer
control circuit can be controlled exactly. According to
requirements, user can set program by using control panel, which
makes sure that sensitivity setting is flexible, reliable and
3. Compound circuit design
The equipment has a counter that registers the number of persons
passed through and the number of alarms. The counter uses Photoelectric Beam Detector, which can respond quickly
and sends the identifiable signal to computer, then decreases the false alarms, the unwanted alarms and false
4. DSP technology
The equipment uses digital signal processor to get reliable
function of the metal detector, versatile features, and user
friendly operation. In addition, this provides the best
5. Adjustable sensitivity
There is 100-step adjustable sensitivity in each detecting zone,
and user can define the sensitivity of each individual zone and
system-level sensitivity according to application required.
6. Password protection
System password is 4 digital, which can be set by user. ONLY the
password has been inputted correctly that user can change program,
sensitivity and other parameters.
7. Serial communication
The equipment can connect to computer through the retained data
communication interface (RS-485, RS-232).
8. Modular design
With modular design, the equipment is installed easily and user can
remove the faults quickly.
9. The best anti-impact performance
The equipment has the best anti-impact performance under the
condition that nobody passes through the WTMD.
10. Electromagnetic sine wave field technology
Transmitter sine-wave causes decaying eddy currents in metal
objects inside the sensing area of the WTMD. The
signal induces to the receiver by the eddy currents is sampled and
processed in the electronics unit.
