Electronic magnetic detector loop detection count input counter shift vehicle alarm

It is responsible for detecting any type of metal ground even through a tar road. This system avoids, in particular, an automatic lifting barrier closes on a vehicle. The device is completely invisible because the detection is made by a buried electrical cable. Automatic vehicle counting system. • Electromagnetic Loop This type of detector is used for the posts of permanent traffic measurements. It is constituted by a metallic conductor located in a notch in the sawn surface of the road following a standardized rectangular.
The transition-metal-forming EVERY vehicles disturb the electromagnetic field induced by the electrical current sent to the driver. The data are stored and transmitted at regular intervals by cables to a central computer process. This widely used sensor still has some investment disadvantages: it is necessary to saw off the floor to install the loops, they are destroyed during repairs or movements of the road. The data correspond directly to a number of vehicles.
