Loop Detector For Long Vehicle Detection troubleshooting

Inductive Vehicle Loop Detector For Long Vehicle Detection

JUTAI as a reliable dual channel loop detectors manufacturer, made this device connects to your gate control panel and allows your gate to open automatically when a vehicle enters the 'Loop' hidden in your drive. This vehicle induction loop presence detector works in conjunction with all our gate systems. It can be used to trigger the gate opening or fitted for protection, to prevent the gate from closing. JUTAI loop detector for long vehicle detection, which is the perfect solution for induction loop traffic detector system.

Dual Channel Loop Detectors Switch Instruction

1. Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way Dip switch setting.
2. User can select 8 different setting by changing the setting of the dip-switch to different modes as in the Dip-switch setting tables below.Dip switch 6,7 and 8 for CH1 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.
3. Dip switch 3,4 and 5 for CH2 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.

JUTAI Inductive Vehicle Loop Detector For Long Vehicle Detection not only can be used in parking, autogate, rolling shutter auto control solution, it also can be used in the traffic control system solution

Do you know why?

1.The inductive range is from 20uh-2000uf, nearly all types of different vehicle can be detector (bike, motorcycle, bus, car,truck,tailer,ect)

2.JUTAI dual channel loop detector is designed to accommodate numerous applications, can be adjusted intelligently to any environments and virtually eliminating false detection.

3.On the front panel, the four selectable loop frequencies (20~80KHz) can completely eliminate any crosstalk. If intermittence happen or failed loops get self restored, the detector will resume to normal operation without manually reset the detector.

4.Two separate output relays:  

Output A is presence output. Can be extended for 0, 2, 5, 8, 10, 15, 20 or 30 seconds, programmable with external DIP switches.  

Output B, programmable with external DIP switches, provides presence, pulse on entry, pulse on exit, or failed output. 8. By setting an external DIP switch, both outputs can be delayed for 2 seconds; this allows the detector to ignore vehicles passing over the loop faster than 5 miles per hour. best loop detector for long vehicle detection.
