Dual Channel Vehicle Detector

Name:Dual Channel Vehicle Detector
loop detector

loop detectors in recent years have become a popular tool having innumerable applications in policing, right from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of theloop detector.

The loop consists of several loops of wire and consideration should be giving to the loop sensitivity when installing on different surfaces. Setting the correct sensitivity allows the loop to operate with maximum detection (16 levels via a trimpot). When detection occurs, the detector energises 2 relays for the output (each can be configured individually). This energising of the relay can be configured into different modes, by selecting the respective dip switch.

The LD-200 Enhanced Vehicle detector is also provided with an integral fault relay, which will provide an output in the event of a loop fault condition.

* Compact Size: the compact and well engineered housing Combines all of the industry requirements regarding Features and functionality and allows this detector to be Incorporated into any or existing traffic detection system.

*Diagnostic Capabilities: Comprehensive diagnostics Capabilities allow for accurate diagnosis of loop and Installation problems.

*Selectable Presence Time: The output of the presence Relay can be selected to limit a detect output to a fixed time(time>30 minutes)while a vehicle remains on the loop.

*Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.

Direction Detection:
If vehicle moves from CH1 to CH2, then CH1 relay output; if vehicle moves from CH2 to CH1, then CH2 relay output.
Sensitivity Selection:

Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.

*Traffic Control Application
*Vehicle Counting
*Toll Systems
*Traffic Analysis
*Parking Control Application

*Operation Temp: -40? to +70? (-111? to +158?).
*Humidity: Up to 95% relative humidity without condensation.
*Fault Output:Blinks slowly: It maybe because the loop is short circuit or the no:of turns is not enough.
*Circuit Protection: Conformal coating over the PCB and all components.
*Blinks faster: It maybe because the loop is open or the no: of turns is too many.
