45 Detection Max can expand 90 Detection walk through metal detector

This WTMD in part by the electronic control unit and two detectors. The electronic control unit includes a variable magnetic field generators, receivers, signal processors and process controllers; the detector contains two transmitting and receiving antennas, which are pre-installed on the inner side of the two door panels. Among the above parts are connected via cables (electronic control unit out lead two pcs of cables, these cables connect control unit to the two detectors).
WTMD outframe is consists of two door panels and a main box. One side of the door panels has power connector at the bottom, while the other side has not. Main box are fixed with two door panels to shape the door arch. Electronic control unit are fixed inside the main box. Inside the two door plates, LED light bars are installed from top to bottom.

l Sensitivity – is used to define parameters for alarm metal object size. Raise the sensitivity; smaller metal objects can be detected.

l Discriminating – the ability for WTMD to distinguish metals (especial metal weapon) and other articles. WTMD alarm rate can indicate the ability to WTMD discriminating. It is affected by many factors, such as sensitivity levels, passengers’ body shape, season (temperature) and so on.

l Useless alarm – alarm caused by carrying harmless metal objects

l False alarm - alarm caused by the reasons other than by a metal object (such as electronic interference). For WTMD, the alarm caused by the metal objects (useful or useless) is not false alarms.

l Alarm rates - alarm times (caused by metal objects) / Passengers *100%. Alarm rate is affected by WTMD discriminating ability. If discriminating ability is poor, for example: there are many alarms caused by harmless metal objects, the alarm rate will be higher. Alarm rates don’t include alarms caused by electronic interference and other reasons.

l Pass rate - at a given time, maximum number of passengers allowed. Pass rate shows the WTMD recover ability after the former detect. In practice, due to the check process and the maximum walk speed and other factors, while the maximum rate is only for theoretical.

l Speed response –the ability for WTMD to maintain the same level of sensitivity, while inspecting passenger walk at different speed.  

l Calibration - in order to achieve optimum performance; set the parameter values for WTMD at the installation site.

l Side by side use - if two or more WTMD work side by side, their electromagnetic field will affect each other. Choose different frequency to reduce the interference.

l Operating Frequency - frequency generated by WTMD electromagnetic field. During the calibration at site, choose different frequencies at the lowest interference level. WTMDs can be installed side by side
