Blinks Slowly Traffic Loop Detector -40 To 70 Celsius Degree For Parking Control

1. Description of magetic loop detectors (LD-200):

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.

4.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.
