A great scientific innovation must lead to a great technological breakthrough. Tck•w portable rope testers weigh only 1.8 kg, about 1/6~1/25 of the weight of conventional ndt testers. The sensitivity of tck•w sensors could reach 5v/mt, and about 700times higher than conventional sensors. The gap between sensor and wire rope is about 20-30mm which achieves non-contact inspection, it does not affected by grease, normal warped wire, and rope-running speed which shown that passing-through capacity is good. When an inspection is completed, tck•w rope testers are capable to display testing data, flaw graph, data table, and test report on lcd screen. After connected to a computer and printer, a formal test report could be printed, which provides scientific reference for users to use wire ropes more safely and replace wire rope more properly. Key features 1. High inspection precision, strong resolution and stable performance: “weak magnetism sensor” technology invented uniquely by our company, its sensitivity is 700 times higher than traditional tester. The sensor has strong resolution, and can inspect quantitatively actual wire rope flaws under various working status. 2. Small volume and light weight: the weight of w portable flaw detector is less than 2kg, which is only 1/6—1/20 of similar products at home and abroad. 3. Easy operation: inspection system realizes intelligent “fool” operation; on-line lock or unlock only needs 1 second; it only needs one person to operate, and the operation is much easier than using a mobile phone.

The entire testing and operation process can be controlled by the background software. Two kinds of test modes ensure absolute time delay parameters of MU and complete the SMV response time test accurately. The timing function makes tests on MU's clock synchronization and time accuracy, etc time characteristics. SMV analysis analyzes SMV and GOOSE messages output by MU in real-time. It tests the MU's self-checking and fault process by SMV quality bit, signal remark in GOOSE or the defined warning information in GOOSE. The electric quantity in SMV can display the wave, binary status and previous displacement time. The SMV and GOOSE abnormal output by MU can be judged and analyzed by multi abnormal SMV detection systems.
