VEHICLE LOOP DETECTOR

The LD160 is a single channel inductive loop detector. The LD160 is compatible with most single channel detectors on the market and is easy to set-up and install.

Typical applications in the traffic environment are traffic control (traffic lights), toll systems and vehicle counting.

Standard features of the detector are :

· Reset Switch.

The reset switch enables the detector to be manually reset during commissioning and testing. This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection.

· Switch selectable Sensitivity.

Eight sensitivity settings are available on the switches to allow flexibility in configuration and application.

· Switch selectable Frequency.

Two frequency settings are available to prevent cross-talk between adjacent loops.

· Fault Relay feature.

The Fault relay is activated when a fault has occurred on the loop.
