Abstract
The invention relates to a reverse loading device. An eddy current sensor reverse loading device comprises an eddy current sensor, a signal cable, a junction box and a reverse loading support assembly formed by an eddy current sensor protection tube, first and third eddy current sensor protection tube fasteners, a second eddy current sensor protection tube fastener with a knurled nut, first, second and third o-shaped seal rings, first, second and third lock nuts and a reverse loading support process adapter. An outer surface of an upper screw thread of the eddy current sensor protection tube is provided with a groove which matches with a convex pin key of an upper portion of the first eddy current sensor protection tube fastener. The groove is used for ensuring that the eddy current sensor protection tube is not rotated when the knurled nut is screwed.
