Vehicle loop detector           BRD01          

Description:
This is a single channel channel inductive loop detectors which is based on the changes in the inductance that are caused by metal parts of a vehicle. These signals are then picked up & evaluated by a microprocessor and when operation voltage is applied, its calibrations becomes automated thus resulting in ease of use.
