Application:

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

Functional description:

NBLD200 has two-way output relays. Two outputs of them are unlimited when the corresponding loop is permanently covered,while the others are multi-mode that can be set by users. The direction detecting Function can be used to statistics the vehicle flux. 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 thanks to automatic calibration when the operating voltage is applied.
