Inductive Vehicle Detector

How does it work?


The principle of operation of the equipment consists of the detection of a metallic mass by means of the measurement of inductance of a detection coil. The coil is part of an oscillator circuit that generates a magnetic field. When this field is crossed by a vehicle, the oscillator frequency changes. This variation is detected by a microprocessor circuit that determines, based on the equipment configuration, if the exit signal must be generated.
