Reliable Vehicle Detection for Access Control Systems
Inductive loop detectors such as the Carlo Gavazzi LDP2PA2DU24 detect vehicles by measuring changes in the electromagnetic field generated by buried loop sensors. When a metallic vehicle enters the detection area, the change in inductance is analysed and the relay outputs are activated.
The LD series provides advanced configuration options including sensitivity adjustment, frequency management and loop fault diagnostics. These features allow reliable operation in parking facilities, industrial entrances and automated barrier systems where accurate vehicle detection is required.
Typical Applications
- Automatic gates and barrier systems.
- Parking access control installations.
- Vehicle counting and traffic monitoring.
- Industrial entrance automation.
- Bollard and security access systems.
- Drive-through vehicle detection systems.
