Vehicle Metal Detector Boom Barrier Single Channel Loop Detector Pd132

Product description

Loop detectors are used wherever vehicles have to be detected, for example: monitoring and safe guarding

access ways or counting vehicles. The output signal can be used for controlling door and gate drive mechanisms,

operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.

SINOMATIC loop detector with direction detecting function that can be used to statistics the vehicle flux.

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.

Application scope

♦ Parking lot entrances vehicle detection
♦ Parking lot space information acquisition system
♦ Electronic police traffic lights snap shot system
♦ Traffic monitoring system

Main Features:

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 1s or 0.5s ;

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 .
