š Key Concepts
ā¢ Condition-based maintenance (CBM) focuses on monitoring equipment condition rather than fixed time intervals
ā¢ Different techniques detect different kinds of developing faults: mechanical wear, lubrication breakdown, overheating, or leaks
ā¢ Which method shows early changes in mechanical condition and balance of rotating machinery over time
š Think About
ā¢ Ask yourself: which technique most directly shows changes in how smoothly bearings, gears, and rotating parts are running as they wear?
ā¢ Which method is commonly trended over time on pumps, motors, and turbines to catch misalignment or bearing damage before failure?
ā¢ Which option is especially valuable for detecting imbalance, looseness, and bearing defects that come from physical wear?

Before You Answer
ā¢ Identify which method is best at detecting misalignment, imbalance, and bearing defects in rotating machinery
ā¢ Decide which technique is most often used for trending mechanical deterioration over time, not just temperature or fluid quality
ā¢ Make sure you separate methods that mainly detect heat or fluid contamination from the one that best tracks changes in mechanical motion due to wear
