170kHz Single Channel Loop Detector 10ms Automatic Calibration Time

PD132 DC 24V 2s To 5s Automatic Calibration Time Single Channel Vehicle Loop Detector

Product description

PD132 single loop detector is used for wherever vehicles have to be detected , for example for monitoring and

safe-guarding access ways 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 .

PRODUCT APPLICATIONS

Automatic Gate
Traffic Light System
Gate Drive Mechanisms
Operating Barriers
Parking Guidance System
Activating Card Dispensers in Parking Lots

PRODUCT TECHNICIAL SPECIFICATIONS

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 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 .

PRODUCT INSTALLATION

The detector must be installed in a convenient weatherproof location as close to the loop as possible. Installation

location must choose to stay away from the heat source, it around other devices must maintain a distance of at least

10mm (mustn’t fix cling to the cabinet). A correct loop configuration and detector installation will ensure a successful

inductive loop detection system. Loop of several important parameters include: loop figure, size, and turns, install

methods (details as “Loop installation guide”).

Work indicator

Detector will enter into the self-calibration condition with the green LED flash, red LED extinguish once on power,

this procession will last 1 second. .the vehicle should not on the loops within the self-calibration. The green LED will

not flash, he red LED extinguish after self-calibration. When the vehicle past over the loop ,the red LED on.

Operation and Indication

While the detector is tuning, the green Channel LED and red Power LED will be turn on. It remain about 2 seconds,

then the green LED turn off. If a loop fault exists the Channel LED will come on and flash indicating a fault. If the fault

is self-healing the detector will continue to operate. The green channel LED will also glow whenever a vehicle is

detected passing over the inductive loop. The red Power LED at the top of the unit will remain on to indicate that the

unit is powered.

Frequency

To eliminate interference of two neighbouring wire loops or loop detectors, the frequency can be altered.

Sensitivity

The sensitivity of the detector allows the detector to be selective as to the change of inductance necessary to produce

an output. There are four sensitivity selections and are set as follows by DIP3 and DIP4 Switch.
