Item NO.:Single Channel Inductive Loop Detector Frequency Adjustable CE & RoHS

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.

vehicle loop detector

single channel loop detector


Features :

1) Reset Switch : The reset switch enables the detector to be manually reset during  commissioning and testing . This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection ;
2) Selectable Pulse Time : This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 Seconds ;
3) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop ;
4) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles ;
5) Switch Selectable Sensibility : 11 levers adjustable sensitivity setting are available on the switches to allow flexibility in configuration ;
6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;
7) Filter Option : This option is used to provide a delay between detection of the vehicle and  switchiing of the output relay . This relay is normally used to prevent false detection of small or fast moving objects ;
8) Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods .

Symptoms Solution
If the detector is not working? Press reset
If red led indicator is not fully lit? Check for power supply
If green led indicator ? Blinks slowly?  It maybe because the loop is short circuit or the no: of turns is not enough
Blinks faster?  It maybe because the loop is open or the no: of turns is too many.
 If no: of turns is not enough? Lower the frequency (if the frequency is still too high, you must add more turns).
If no: of turns is too many? Higher the frequency (if the frequency is still too low, you must remove some turns).
