A procedure and apparatus for analyzing wear particles present in a flowing fluid and for continuously determining the wear situation of mechanical contacts. The fluid is conducted to a point of examination in a measuring passage (2), stopped, and imaged there with a photoelectric detector (8). With a data processing device (13), the image in analog form is digitized, and from the image are, by methods of digital image processing, automatically determined the central index values in view of degree of purity and/or wear situation, which describe the size, size distribution, shape, surface structure, light transmittance and/or colour of the particles in the fluid. The information thus obtained is classified with the aid of the index values found and of a predetermined set of deduction rules, such as an expert system, and the wear situation of sliding and/or rolling mechanical contacts in contact with the fluid is determined. |
