WS-PD132 DC12/24V single channel loop detector

Product Description

PD132 single loop detector is used for wherever vehicles have to be detected , for example  for monitoring and safe-guarding accessways or for counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems or activating card dispensers in parking lots . PD132 has two-way output relays , one is unlimited output when the loop is temporarily covered , while the other is multi-mode that can be set by users



1) 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 ;

2) Selectable Pulse Time : This feature sets the length of time that the pulse relay will be

    energized for 1 Second or 0.5 Seconds ;

3) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a

    vehicle or when the vehicle leaves the loop ;

4) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used  

    to prevent loss of detection of high-bed vehicles ;

5) Switch Selectable Sensibility : 4 sensitivity setting are available on the switches to allow

    flexibility in configuration ;

6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk

    between adjacent loops ;

7) Filter Option : This option is used to provide a delay between detection of the vehicle and

    switchiing 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 ensure detection of the vehicle will be maintained

    when the vehicle is parked over the loop for extended periods
