MPI57 Magnetic Particle Inspection Equipment   The magnetoscope MPI57 checks for cracks in the crankshaft. Thanks to the magnetic inspection, it is possible to locate and evaluate the small cracks or hollows, better than by a visual inspection. By sprinkling the crankshaft with detecting fluid containing magnetic particles, made fluorescent by the ultraviolet Light, the contrast between the piece and the cracks becomes stronger, because these particles concentrate in the cracks area. This way it is easy to check the conditions of the crankshaft, and see if it is possible to rebuild it.
