Oil debris monitoring system notes

1.  MS4110 is an example of an oil debris monitoring system
2. OODM cannot predict failure 
3. Only gives data on wear particle generation rate
4. Correlating wear particle generation to failure is system-specific
5. Metalscan system can isolate ferrous and non-ferrous
6. Chipcheck system can also identify alloys of the metal using spectroscopy
7. M50 is bearing grade steel
8. If detected, don't use the machine
9. Silver is used as coatings for the bearings
10. Silver in oil indicates superficial damage
11. Ferrous particles are detected using eddy current 
12. Nonferrous particles are detected using permeability-based detection
13. Usually, opposite phase signals are obtained for ferrous and non-ferrous
14. The only parameter on the sensor is the phase angle
15. The interquartile demodulation technique is used to detect the chips.
16. Data communication is through Modbus or TCP protocol
