#Vehicle Loop Detector #Single loop detector #PD132 single loop detector #Single Channel Inductive Detector #Loop Detector
Features:
The Vehicle Loop Detector is mainly used to detect the existence and passing of vehicles
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
Selectable Pulse Time: This feature sets the length of time 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 on 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
Switch Selectable Sensibility: 4 sensitivity setting are available on the switches to allow flexibility in configuration
Switch Selectable Frequency: 4 frequency settings are available to prevent cross-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 .
