Detailed Product Description

This 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 thanks to automatic calibration when the operating voltage is applied.

u         to eliminate interference of two neighboring wire loops

u         to eliminate interference of two neighboring loop detectors

u         to eliminate interference of two neighboring distribution cables (loop detectors)

Attention:

 When using more than 2 Detectors, please select different frequencies ,and screened cables for Detector or connecting cables widely separated

Sensitivity:

 In order to calibrate on site the wire loop to the loop detector, the sensitivity can be adjusted on the front of the housing by means of a three-stage sliding switch.

Ø  High:     high sensitivity (e.g. also bicycles can be detected)

Ø  Medium:  medium sensitivity (e.g. for automobiles)

Ø  Low:     low sensitivity (preferably Lorries will be detected)

Ensure that the loop is NOT activated when making these adjustments.
