Reliable Vehicle Detection for Access Control Systems
Inductive loop detectors such as the Carlo Gavazzi LDP1SA1BM24 operate by measuring changes in inductance from a buried wire loop when a metallic vehicle enters the detection area. The microprocessor evaluates these changes and activates the relay output when a vehicle is detected.
The LD series is designed for parking facilities, drive-through systems and industrial access points where reliable vehicle presence detection is required. Programmable operating modes and adjustable sensitivity allow the detector to be adapted to different loop installations and environmental conditions.
Typical Applications
- Automatic gates and barriers.
- Vehicle access control systems.
- Parking management installations.
- Drive-through detection systems.
- Industrial doors and security fences.
- Traffic monitoring and vehicle counting applications.
