Every failing machine tells you first — in vibration. These free primers take you from zero to reading a spectrum with confidence, then hand you a verifiable badge for the climb.
The path is a gated climb. Pass a track's courses and its badge qualifying exam to earn the badge — which unlocks the next track. Your progress is remembered on this device; the trace below lights up as you go.

What vibration is, why machines shake, and how amplitude, frequency and phase describe every fault.
Time to frequency: sampling, the FFT, windows and resolution — read a spectrum without guessing.
Pick the right accelerometer, mounting and sample rate so your measurement is honest, not artefact.
Routes, triax points, units and bands — set up a repeatable measurement that trends cleanly.
Unbalance, misalignment, looseness — match the spectrum signature to the mechanical cause.
BPFO, BPFI, gear mesh and envelope demodulation — catch defects while they're still early.
Single- and two-plane balancing and shaft alignment — fix the fault, not just read it.
Natural frequencies, mode shapes and resonance — why a small force becomes a big problem.
Sound vs vibration, weighting and noise sources — TIERA's home turf, made approachable.
Automatic anomaly detection and the data flywheel — where the analyst and the model meet.
Free beginner primers to make vibration click — built by the team that makes the instruments.
Short, interactive and self-paced. Finish a course and the engine issues a completion certificate on the spot. Finish a track and earn a shareable badge. No sign-up, no cost — just the fundamentals, done properly.
TIERA 101 gives you working fundamentals. It is not equivalent to, nor a substitute for, ISO 18436 Category I–IV vibration-analyst certification.
TIERA's formal ISO 18436 Category I–IV programme is separate and paid. Ask us about the certified track when you're ready to go pro.
