Loop Detection Coil With Top Quality Traffic Loop Detector Coil
Loop Detection Coil
Loop detection coil lifespan is longer. if you want to add a wire slot brackets, you need to be wider. Check the condition of the underground reinforcement (cement floor), determine the depth of the buried line, or add or subtract the number of coils. It is only possible to embed the line when the road surface is dry and fill the seal. The lead length should be reserved before embedding the loop detection coil. When the wire is buried, each loop should be close to the top and bottom. when the two leads are started at the corner of the loop detection coil, even if they are wrapped around each other, they are buried in the lead slot.
Check the inductance and insulation resistance with a loop detection coil measuring instrument. If the specification is met, the embedding of the loop detector coil is completed after the glue is dried. If it is not appropriate, it needs to be reprocessed. The total length of the loop sensor coil should be about 24 meters. The ground-sensing line should be made of high-temperature insulated wire with a cross-section larger than 0.25 square millimeter. The cutting machine can be used to cut the groove on the hard concrete floor. The depth is about 5-7cm. The width is etched to a thickness of 5mm. The line is placed in circle one by one, and the groove cover is cemented. Noted that the loop sensor coil does not float out of the ground. When placing the wholesaler loop coil, be careful not to damage the insulation of the wire to avoid leakage or short circuit. Good Quality Loop Coil and feeders are the most important and easily obstructed parts. Must pay enough attention. Before the slotting. Check whether the road surface is strong and follow the overall technical conditions of the system to select is strong and follow the overall technical conditions of the system to select the position where the loop detector coil is buried. Draw a slotted dimension line. Use the slotting machine to construct according to the figure.
Loose embedding of the coil: The local coil cannot be firmly fixed in the slot. The vibration of the car over the road surface will cause the deformation of the loop detection coil inside the slot, changing the initial inductance of the sense of the ground. At this point, the sensor must be reset before it can work normally. Causes the vehicle detector to fail to detect. The solution is to pour the malted asphalt into it for fixing. It is preferable to have an LC inductor to measure the magnitude of the sensor of the loop detection coil. The inductance used to confirm the number of turns of the inductive coil is between 100uH and 300uH. The vehicle detector can be used in stable operation within the scope of use. The material of traffic detection coil should meet with the market requirement.
