PD132 Single Channel Inductive Vehicle Loop Detector for the Car Parking Lot

Descrição de PD132 Single Channel Inductive Vehicle Loop Detector for the Car Parking Lot

The Vehicle Loop Detector is mainly used to detect the existence and passing of vehicles;Reset : The reset 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
Selectable Pulse : This feature sets the length of that the pulse relay will be energized for 1 Second or 0.5 Seconds;Pulse Relay Selection: The Pulse Relay may be configured to energize detection of a vehicle or when the vehicle leaves the loop
Sensitivity Boost : This feature sets the undetected level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles
Selectable Sensibility: 4 sensitivity setting are available the switches to allow flexibility in configuration; Selectable Frequency: 4 frequency settings are available to prevent -talk between adjacent loops
Filter Option: This option is used to provide a delay between detection of the vehicle and switching of the output relay . This relay is normally used to prevent false detection of small or fast moving objects;Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods.
