Product Description

PD-232 AC 220V Dual Channel 4 Steps Switch Adjustable Inductive Car Vehicle Loop Detector



PD-232 loop detector is a dual microprocessor based detector designed specifically for parking and vehicle access control applications.The primary function of the detector is to detect vehicle presence by means of an inductance change caused by the vehicle passing over a wire loop buried under the road surface.

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
