SEWO-T2800 is a single channel inductive loop detector. 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.

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.

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

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

Low: low sensitivity (preferably Lorries will be detected)

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

Application

SEWO-T2800 single loop detector is used wherever vehicles have to be detected. For example, monitoring and guarding safety of access ways or 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 parking systems.
