| OELCHECK Test equipment: | Spectro Laser Net Fines-C |
| Sample quantity needed: | 10 ml |
| Unit: | Number of particles per 100 ml |
| Test result: | Number of particles per 100 ml Purity level according ISO Number and size of particles according ISO Number of particles in different categories Pictures from the contour of the particles |
| Operating time: | About 10 minutes |
| Analysis of: | Gear oil, hydraulic- and circular lubrication oil |
| Brief description: | The homogenised sample is pumped with continues speed through a flow-through cell which is illuminated by a very bright laser light. The particles block the laser light and the shape of the particles becomes visible for the detector by zooming in an optical system. Pictures from the enlarged particles are made with a high speed CCD camera and captured in black and white. The shape and size of the particles is analysed and assigned in defined categories like fatigue wear, sliding wear, cutting wear, non-metallic particles or water drops. Additionally the number and size of the particles can be specified acc. ISO 4406 and SAE AS 4049, like it’s done by the standard particle count. |
| Statement: | With the help of the optical particle analysis it´s possible, beside the classical particle count, to take a picture from the single particles in the oil stream. The result is shown in the lab report in form of four additional pictures. The test is a good addition to the element analysis acc. OES and the PQ-Index. These tests show only particles < 5 µm respectively magnetic particles and the standard particle count doesn`t make a difference between hard and soft particles. |
