Walk Through Metal Detector (AT-IIIA)

The AT-IIIA 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 Detector). With 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. 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.

There are high-brightness digitron display panel and warning LEDs. Displaying the number of persons passed through, the number of alarm, alarm zone and intensity of alarm. 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 interference immunity.

User can setting the operating frequency, and makes several equipments working together with interference immunity. The equipment can connect to computer through the retained data communication interface (RS-485, RS-232). With modular design, the equipment is installed easily and user can remove the faults quickly.

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. The equipment is based on weak electromagnetic field technology, so its use according the instructions does NOT, pursuant to currently international safety standard, cause and health risks to pregnant women, persons with pacemaker, floppy disk, films and tapes.
