B. The operation theory of  loop detector

The LD110 is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use due to the automatic calibration when the operating voltage is applied.

 

C. Loop Detector features:

 

1.The NBLD-100 is intelligent,extremely flexible and very affordable product.

2.The NBLD- 100 is designed to accommodate numerous applications,

can be adjusted intelligently to any environments and virtually eliminating false detection.

 3.Four selectable loop frequencies(40~80KHz),succeed in solving the interference/crosstalk of       nearby loop by using different frequency; 

4.Sensitivity with 16grades selection,apply for different cars.

5.Two color LED status indicator,Power and Loop Fault indication.

6. No warm up required.

D. Applications of Detector

 

Loop detectors are used wherever vehicles have to be detected. Like monitoring and safe guarding access ways for counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, road barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.
