Vehicle Counting Single Channel Loop Detector ETC Control OEM / ODM

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.

Specifications:

Features                                          

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. 

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.

Applications: 

Traffic Control Application
Vehicle Counting
Toll Systems
Autogate control
Traffic Analysis
ETC Control
traffic signal control
