Loop detectors in recent years have become a popular tool having innumerable applications in policing, right from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of the loop detector.
The digital technology of the loop detector enables the equipment to sense a change in the inductance of the loop as soon as it detects the metal object in its path. The inductive loop which detects the object is made of insulated electrical wire (32/020; 32 Strand, 2mm
diameter) and is arranged either as a square or rectangle shape.
The loop consists of several loops of wire and consideration should be giving to the loop sensitivity when installing on different surfaces. Setting the correct sensitivity allows the loop to operate with maximum detection (16 levels via a trimpot). When detection occurs, the detector energises 2 relays for the output (each can be configured individually). This energising of the relay can be configured into different modes, by selecting the respective dip switch.

The detecting range can be from 15UH-2000UH, the loop detector can be in stable work status no matter the inductive value how to changes.
Many type vehicles can be detected:It can detect many type vehicles with different height and weight, like Motorcycle, Truck, Car, Bus, etc.
Adapt to the bad environment:All of our loop detector we do temperature test and corrosion test(-40 degree to 70 degree), let it always keep the outstanding performance.
Installation Diagram And Application
All permanent loop installations should be installed in the roadway by cutting slots with a masonry cutting discor similar device. A 45° crosscut should be made across the loop corners to reduce the chance of damage that can be caused to the loop wire insulation at right angle corners.
