PD132 Single Channel Inductive Vehicle Loop Detector for Car Parking Lot Vehicle Loop Detector ENGLISH VERSION Features:The Vehicle Loop Detector is mainly used to detect the existence and passing of vehiclesReset 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 detectionSelectable Pulse Time: This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 SecondsPulse Relay Selection: The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loopSensitivity Boost : This feature sets the undetected level to maximum sensitivity and is used to prevent loss of detection of high-bed vehiclesSwitch Selectable Sensibility: 4 sensitivity setting are available on the switches to allow flexibility in configurationSwitch Selectable Frequency: 4 frequency settings are available to prevent cross-talk between adjacent loopsFilter 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 objectsPermanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods.
