Vehicle Detector Coil With Hot Sale Vehicle Loop Detector For Sale
Vehicle Detector Coil
Vehicle detector coil material is very strict. Due to it has an effect on vehicle loop detector working. The vehicle detector consists of a surrounding coil and an inductive digital circuit board. Anti-corrosion ground coil (wire material adopts special anti-corrosion line for grounding, has the characteristics of wear resistance and corrosion resistance), the coil is buried in the underground 10-15CM, as long as there is a vehicle passing on the road, the coil generates an induced current and transmits it to the circuit board, and then the circuit The board generates a TTL level signal or a dry junction signal to the controller or the electric gate. The vehicle detector coil in front of the entrance ticket box is mainly matched with the entrance control board and the automatic card issuing machine and realizes the function of “having a car card” and “one car only one card. When the vehicle enters the signal and presses the card take-up button, the card-issuing card-issuing machine automatically issues the card, and the vehicle detector under the gate railing is matched with the gate control board, which acts as a flood prevention function when the vehicle passes by. The car automatically stops after the car has passed. Generally, polyethylene AWG16~22 multi-core high-temperature sheathed wire can be used, and PVC insulated wire is not used.
The traffic detector coil shape and slotting method: the coil is generally rectangular, and the four corners are chamfered at 45 degrees to avoid the sharp cut loop detector coil cable. Coil construction steps: Pavement line, according to the object of detection, determine the coil size, to avoid damage to the cable insulation by sharp corners, set the kerf: the depth is generally 50~80mm. It should be ensured that the uppermost cable in the slot is 30mm or more from the ground, and the slot width is generally 4~8mm. It should be larger than the cable diameter. Cut the feeder cable trough, remove the acute angle in the trough, clean the debris, and check whether the bottom of the trough is flat. The cable of the whole inductor coil (including the rectangular vehicle loop detector coil and the feeder) should be free of joints, and the cables should be lined up from the bottom to the top in the groove and pressed until the total number of designs is completed;feeders (from rectangular coils to detectors) shall be twisted and extended to the detector and twisted at least 20 times per meter.
Vehicle detector coil cable must be fixed with a plastic foam rod about 3cm long every 20~30cm, which can prevent the cable from floating up during the caulking; Caulking: The gap in the tank must be filled and integrated into the road to prevent the coil from vibrating when there is a passing vehicle. Cement, asphalt or epoxy resin can be used for the cement pavement, and asphalt can only be used as the caulking material for the asphalt pavement.
