CINCINNATI AGP series vehicle detectors are compact electronic devices designed to detect the presence or transit of a vehicle over a selected area. Detection is accomplished by vehicle presence or passage over a loop of a few turns of wire embedded in the roadway of an entrance and exit lane. The loop, whose leads extend to the detector, is fed by a high-frequency signal. Vehicle proximity produces an increase in the signal frequency which is detected and causes It’s output relay to energize and actuate external equipment such as gates, ticket dispensers, vehicle counters, traffic lights, signals, etc.

The CVD Series vehicle detector is completely self-contained with a built-in electronically regulated power supply to compensate for power line voltage variations.  The power supply supports stable detector operation during power line dropout for 40 milliseconds minimum with low line voltage.  The loop frequency is determined by the loop inductance and in the internal feedback network. All circuits use solid state components mounted on a glass epoxy printed circuit board.
