DETECTION OF CROSS SECTIONAL AREA VARIATION IN A WIRE ROPE - CASE 2 |
| 摘要 |
Cross sectional area variations in an elongate object such as a wire rope are detected by axially magnetizing a section of the rope in opposing axial directions and detecting radial flux variations to or from the rope by means of a string of interconnected non-inductive transducers such as Hall-effect devices.
