Single Channel Vehicle Detector

Description

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 the loop detector.

The digital technology of the loop detector enables the equipment to sense a change in the inductance of the loop as soon as it detects the metal object in its path.
The inductive loop which detects the object is made of insulated electrical wire (32/020; 32 Strand, 2mm diameter) and is arranged either as a square or
rectangle shape. 

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-100 Enhanced Vehicle detector is also provided with an integral fault relay, which will provide an output in the event of a loop fault condition.

Features Applications

Compact Size: the compact and well engineered housing Traffic Control Application

Combines all of the industry requirements regarding Vehicle Counting
Features and functionality and allows this detector to be Toll Systems
Incorporated into any or existing traffic detection system. Traffic Analysis
Diagnostic Capabilities: Comprehensive diagnostics Parking Control Application
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.
Two separate output relays:
Presence Relay A is presence output. Can be extended for 0,2,5,8,10,15,20 or 30 seconds, programmable
with external 10 way DIP switches.
Pulse Relay B, programmable with external 10 way DIP switches, provides presence, pulse on entry, pulse on
exit, or failed output.
