Single And Double Channel AC 220V 110V DC 12V 24V Vehicle Loop Detector For Parking Lot Vehicle Detection
PRODUCT INTRODUCTION
The PD-232 is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.

MAIN FEATURES
1)Reset Switch:The reset switch enables the detector to be manually reset during registering and testing and it is a process of system recovery
2)Selectable Pulse Time:This feature sets the length of time that the pulse relay will be lasting for 1S or 0.5 Seconds
3)Pulse Relay Selection:The Pulse Relay may be configured to activate on detection of a vehicle or when the vehicle leaves the loop
4)Sensitivity Reinforcement:This feature sets the un-detecting level to a maximum sensitivity to prevent failing to detect vehicles as big trucks
5)Switch Sensibility Adjustable:4 sensitivity setting are available on the switches to change sensitivity
6)Switch Frequency Adjustable:4 frequency settings are available to prevent signal interference with neighboring loops
7)Filtering 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
8)Permanent Presence Option:This feature ensures the detection of the vehicle will be maintained when the vehicle stays within the loop area for extended periods
