High-Quality Vehicle Loop Detector Easy Installation Loop Detector
High-Quality Vehicle Loop Detector
High-Quality Vehicle Loop Detector easy installation, the small size of high-quality Vehicle Loop Detector. High-quality Vehicle Loop Detector, Vehicle Loop Detector Wiring, How does on inductive Loop Detector Work, Induction Loop Traffic Detector Vehicle Loop Detector Wiring, There are two sets of relays for the grounding power 220v wiring and the grounding coil wiring detector. The two sets of COM terminals are connected to the 12v NO from the gate, the OPEN of one interface gate, and the other is connected to STOP. Vehicle Loop Detector Wiring, How does on inductive Loop Detector Work, Induction Loop Traffic Detector
vehicle loop detector Direction detection (Switch 1=SW1)D 3, D4, D5 and (Switch 2=SW2) D1, D2 can set the detection and output mode, mode, vehicle loop detector specification, Induction Loop Traffic Detector, model 1, If the car is from CH1 to CH2 coil, CH1 relay pulse mode output when the car leaves the CH1 coil. If the car is from CH2 to CH1 coil, CH2 relay pulse mode output when the car leaves the CH2 coil, model 2, Direction detection: If the car is from CH1 to CH2 coil, the CH1 relay has mode output when the car enters the CH2 coil. If the car is from CH2 to CH1 coil, the CH2 relay has mode output when the car enters the CH1 coil. model 3, Direction detection: If the car is from CH1 to CH2 coil, when the car enters the CH1 coil, the CH1 relay has a mode output. If the car is from CH2 to CH1 coil, the CH2 relay has a mode output when the car enters the CH2 coil. model 4, CH1 and CH2 are individually controlled and output in presence mode,
The working principle of the vehicle loop detector working coil, the ground-sensing coil vehicle detector is a vehicle detector based on the principle of electromagnetic induction. It usually embeds a toroidal coil under the road subgrade of the same lane, through a certain working current and the sense of the ground. When the vehicle passes through the coil or stops on the coil, the iron on the vehicle itself will change the magnetic flux in the coil, causing a change in the inductance of the coil loop, and the detector determines the state of the passing vehicle by detecting the change in the inductance. There are two methods for detecting the amount of change in inductance: one is to use phase latch and phase comparator to detect the change of phase; the other is to use the coupling circuit formed by the loop coil to detect the oscillation frequency. High-quality Vehicle Loop Detector,
Installation and Diagnoses:
1. please refer the upside diagrams for loop size and installation
2. we recommend using 0.75mm² multi-core copper wire, the total wire length includes feeder can be up to 500m.
3.the loop should be rectangular and avoid any right angle. the recommended length is from 1.0m-2.0m, the recommended width is from 0.8m-1.2m.
4, The remaining line is connected to the detector at least once every 15 cm.
5. The more the number of coil turns, the lower the frequency, and the lower the number of coils turns, the higher the frequency.
6. The coil should be buried in a position adjacent to the moving coil door.
7. Can detect vehicle speed below 120 kilometers per hour
