Installation and commissioning sense coil to the detector in the best shape at Barrier offer, the coil inductance should be maintained between 100uH-300uH. Under the same circumstances Barrier coil inductance, number of turns and the perimeter of the coil has an important relationship. The smaller circumference, the more the number of turns. Since the road may be buried under a variety of cable lines, steel, and other metal sewer cover material, which will have a significant impact on the actual value of the inductance of the coil, so the table data is only for reference. In the actual construction users should use the inductance inductance inductance tester actual test to determine the actual number of turns of the coil construction, the scope of work as long as the final inductance coil reasonable assurance of (such as between 100uH-300uH). Barrier common faults and repair methods are as follows: Barrier coil embedding loose: within the local sense coil can not be firmly fixed in the nest when the Barrier supply, automotive pressure off road vibrations can cause deformation of the coil nests, change the sense The initial inductance Barrier production, should be operated sensor must be reset after this time. The solution is poured into the melted asphalt to secure it. Barrier's articulated screw loose: articulated screw thread connecting the positive and negative, between the upper and lower bearing contact with the double-headed screws, screw loose if the cause hyponymy not accurate. 80MM with a long iron rod inserted between Ф4 rotating double screw to adjust brake lever to the next place.
