Machinery Fault Diagnosis and Condition Monitoring
The layer that separates a data collector from a diagnostician: what the analyser is doing to your data, how to choose Fmax, lines of resolution and averaging for the fault you are actually hunting, how to read the time waveform, the orbit and the shaft centreline beside the spectrum, how to measure sideband spacing and name the shaft that is modulating, how to place a rolling element bearing on the four stages of failure, and how to write the condition report a planner can schedule a job from.
Free to learn. Verifiable certificate £19 when you pass the final exam (optional, VAT included).

Sample certificate. Optional, issued when you pass the final exam.

Outcome
What you will be able to do
Set Fmax, lines of resolution and averaging for a stated fault and show the arithmetic; recognise a peak that is an artefact of the settings rather than a machine force; read a spectrum, a time waveform, an orbit and a shaft centreline together instead of one at a time; measure sideband spacing and name the shaft or component doing the modulating; identify a rolling element bearing defect, place it on the four stages and set the monitoring interval it justifies; and write a one page condition report that names the fault, the evidence and the action with a date.
- Choose Fmax, lines of resolution and averaging for the fault you are hunting, and show the arithmetic
- Spot a peak that is an artefact of the analyser settings rather than a real machine force
- Read the time waveform, the orbit and the shaft centreline alongside the spectrum
- Measure sideband spacing and name the shaft or component that is modulating the signal
- Identify a rolling element bearing defect and place it on the four stages of failure
- Write a condition report that names the fault, the evidence and the action with a date
Software
None required. A vibration analyser or data collector if your employer has one.
Hardware
None required. Access to one running machine, its nameplate and its bearing part numbers makes the practice tasks worth far more.
