Abstract

Устройство концентрически охватывает проволочный канат или кабель, подлежащий тестированию, и включает средство для создания магнитного поля в канате или кабеле, а также средства для обнаружения изменений потока в созданном магнитном поле. Путем выявления изменений потока в магнитном поле можно определить состояние каната или кабеля.

Claims (1)

  1. Устройство концентрически охватывает проволочный канат или кабель, подлежащий тестированию, и включает средство для создания магнитного поля в канате или кабеле, а также средства для обнаружения изменений потока в созданном магнитном поле. Путем выявления изменений потока в магнитном поле можно определить состояние каната или кабеля.
