How does the GT200 work?
The GT200 works on the principal of dia/para magnetism. All substances carry a magnetic charge that, when stimulated by an impulse of electricity, (static) creates an attraction between the substance being detected and the GT200 unit itself. This is called EMA or Electro Magnetic Attraction. The simple way to explain this technology is to take an inflated balloon and rub it on your hair. A static charge is being created making that balloon “attract” it to say, a wall. Provided that there is enough charge on that balloon, it will remain “attracted” to the wall for an indefinite amount of time. However, once the “charge” has dissipated, the balloon will then “unattached” between itself and fall to the ground. What the GT200 is doing is creating an “attraction” between itself and the substance it wants to detect. Through the Substance Sensor Card and the movement of an operator, an attracting field is created in the card reader that, in turn causes the Receiver”s antenna of the GT200 to â
