Dual Channel Loop Detector Magnetic 20UH - 2000UH , Vehicle Loop Detector Toll Station

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 detector 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.

Desccription:

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.

Applications:

NOBLE vehicle 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.
