Loop Detector
FEATURES:
 |
The front panel 7-segment LED DEFLECTOMETER® provides visual feedback and assistance for setting the correct sensitivity, reading the frequency of the loop, reporting Loop Faults, and indicating Delay & Extension Timing functions. |
|
|
With a typical size vehicle over the roadway loop, the DEFLECTOMETER® functions as a Sensitivity Meter. The optimum sensitivity setting should provide a reading of “5”. You can adjust the DEFLECTOMETER® reading by using the front panel UP or DOWN sensitivity buttons. Automatic quantitative feedback of the loop system operation ensures that the detector is set to the most optimum sensitivity level to detect ALL vehicles, including motorcycles and high-bed vehicles. |
|
|
Following power-up or reset, the DEFLECTOMETER® will indicate a 2 or 3 digit number (quickly flashes) that indicates the loop frequency of the loop & loop network. Keeping your loops separated by at least 5 KHz avoids crosstalk problems and future service calls. |
|
|
10 levels of sensitivity (0 to 9) can be easily set using the UP or DOWN push buttons. |
|
|
Operates on 120VAC and 240VAC. |
|
|
The Loop Fault Monitor continually checks the integrity of the loops and will report and store three types of loop faults; Open Loops, Shorted Loops, and 25% sudden changes in inductance. |
|
|
The Loop Fault Memory uses internal Non-Volatile memory to store and display the current and previous loop faults utilizing the front panel “Loop Fault” LED and DEFLECTOMETER®. A power loss or reset will not delete this memory. A MUST FOR TROUBLESHOOTING! |
|
|
The detector will not drop a Call state if power is lost for a minimum of 4 seconds or less. |
|
|
A 2-second CALL “Delay” time and 2, 5, or 10-second CALL “Extension” time can be provided. |
|
|
Sensitivity boost - user selectable by an internal dip switch |
|
|
8 sensitivity levels - dip switch selectable |
|
|
Self-tuning and complete environmental tracking |
|
|
Loop failure indicator - Indicates current loop failures or loop failures that have occurred |
|
|
Loop failure memory - Stores last record of the last loop failure |
|

Vehicle Loop Detector
Sensitivity selection is simplified by the ULTRAMETER™, which displays the
appropriate sensitivity setting to detect the vehicle positioned on the loop.
Ten sensitivity settings enable finer adjustment of the detection level. And the
four frequency settings provide greater flexibility in preventing crosstalk in
multi-loop applications.
