Oil Sampling/Analysis

Oil lubricated equipment such as gearboxes, transformers, sleeve bearings and pumps have a condition monitoring technique that looks at gases, moisture and particulate matter in the oil. It is important to understand the technique for extracting the oil to obtain a sample that’s representative of the full volume.

Caution needs to be used to relieve pressure, if applicable, and avoid contaminating the oil being sampled. American MTS has the experience and expertise to extract the sample and analyze the lab results. We utilize the most reputable laboratories for analysis.

Steps we take as part of our oil analysis service:

1. Read and check the data on the oil type and machine type for accuracy.
2. Verify that reference data is shown for new oil conditions and that trend data is at an understood frequency (preferably consistent).
3. Check the measured viscosity.
4. Verify elemental wear data and compare to reference and trended data. Use a wear debris atlas to match elements to their possible source.
5. Check the elemental additive data and compare to reference and trended data. Use a wear debris atlas to match elements to their possible source.
6. Verify elemental contamination data along with particle counts and compare with reference and trended data. Use a wear debris atlas to match elements to their possible source.
7. Check moisture/water levels and compare to reference and trended data.
8. Verify the acid number and base number and compare to reference and trended data.
9. Check other analyzed data such as FTIR oxidation levels, flash point, demulsibility, analytical ferrography, etc.
10. Compare any groups of data that are trending toward unacceptable levels and make justifications based on these trends.
11. Compare written results and recommendations with known information on the oil and machine, such as recent changes in environmental or operational conditions or recent oil changes/filtration.
