Information

The loop detector detects the metal object by detecting the change in the inductance of the metal object on the induction coil. The coil is wound by multiple turns of wire, buried under the road, and filled with cement. The coil lead is connected to CHD-DGII. When a metal object passes through the induction coil, the inductance of the conductive coil changes somewhat. This change is detected by CHD-DGII, and it is judged that there is a metal object through the calculation of the internal intelligent controller, and the signal is output through the output relay. Due to the intelligent control function of the microprocessor, the sensitivity of CHD-DGII can adapt to various requirements, and it can also be well matched to induction coils and leads of different sizes.

Loop detector installation guide:
Whether the loop detector works well depends to a large extent on the induction coil it is connected to. Several important parameters of the coil include: coil material, coil shape and whether it is correctly constructed and buried. The following items must be paid attention to when installing loop detector. The loop detector must be installed in a waterproof environment as close as possible to the detection coil.
The loop detector should be used to detect metal objects such as vehicles and bicycles, and is suitable for parking lots, road vehicle toll stations and signal light control systems. Loop detector adopts the most advanced microprocessor technology, which can meet the application in various usage environments. When a metal object passes through a coil buried under the road, because the metal conductor will change the inductance of the coil, the loop detector detects the metal object by detecting the change in the inductance of the coil.
