Single channel inductive loop detectors; adjustable in 3 increments (high .medium. low).
It 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.
