Elevator portable steel wire rope flaw detector

【Detection principle】

The principle of magnetic leakage detection is adopted, that is: the permanent magnet magnetization will import magnetic energy into the wire rope, in the broken wire or wear, the magnetic sensitivity device arranged in the middle of the magnetization capture, the magnetic leakage information is converted into a voltage signal, and finally form the detection of broken wire or wear. The testing principle is strictly based on the international general standards such as the American ASTME1571-11 standard and the European EN 12927-8 standard and the national standard GB / T21837-2008 "ferromagnetic steel wire rope electromagnetic detection method".

【system composition】

The elevator portable steel wire rope flaw detector consists of detection probe (including encoder), data collection card, laptop computer (including data analysis and processing software) and data collection / transmission line.
