Vehicle loop detector
BRD01
Specification
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.
