Device for registering the composition of foreign particles in liquids

摘要

The device contains a feed duct (2) and a registration duct (4), which communicate with one another via a nozzle (3) and through which the test liquid is pumped. Provided in the registration duct (4) there are transparent windows (5) and (6) for passing a luminous flux from the illumination apparatus (7) through the flowing liquid. The device further contains a photosensitive unit (8) for registering the light reflected by the particles present in the liquid. The ratio of the diameters of the nozzle (3) and of the registration duct (4) is from 1/4 to 1/7. The main purpose of the device is the recording of dirt particles in fuels and oils. <IMAGE>
