ISO 20816 Rotating-Machinery Vibration Zone Inspection

• !Dozens to hundreds of machines, each requiring manual RMS computation and Zone lookup — all by hand.
• !Frequency band, integration method, and group thresholds are easy to mis-remember, and conclusions aren't traceable.
• !Results scattered across spreadsheets, with no trend and no red-green overview.

Limit the 10–1000 Hz evaluation band, compute velocity RMS, and apply Zone A/B/C/D thresholds by machine group — band and thresholds are all explicit parameters, so every conclusion can be re-checked.

Core nodes; add or remove steps as needed for your data and standards — the node graph is always editable.

• Per-point mm/s RMS (10–1000 Hz) and a Zone A/B/C/D red-green status list.
• Multi-period inspection trend curves that surface degradation early.
• Thresholds and grouping are explicit and queryable, so conclusions are traceable.
