Vehicle Inductive Loop Presence Detector

Vehicle Presence Detector Controller (Inductive Loop) This device connects to your gate control panel and enables your gate to open automatically when a vehicle enters the 'Loop' hidden in your drive. Vehicle Inductive loop presence detectors work upon the principle of the change of inductance in the coil when the electromagnetic field is disturbed by a metallic object. The coil is a cable loop which is embedded in the roadway whose inductance is altered when crossed over by a vehicle. This vehicle induction loop presence detector works alongside all our gate systems. It is able to be used to trigger the gate opening or fitted for protection, in order to prevent the gate from closing.
