A vibration severity chart only prevents a failure if a Zone C reading turns into a job somebody completes. Oxmaint ingests data from wired and wireless sensors continuously, classifies every reading against the standard your machine group falls under, watches the trend rather than only the threshold, and raises a prioritised work order the moment a developing fault appears. Start a free trial or book a reliability demo to see your own rotating assets trended.
Vibration Monitoring Software
Most sites already collect vibration data. Far fewer can tell you which readings moved this month, which machines are drifting toward Zone C, and which findings became work orders. That gap is where bearings still fail on monitored equipment.
Reading the zones, the way the standard defines them
ISO 20816-3 replaced ISO 10816-3 in 2022, and the zone boundaries carried straight over. A reading judged against either gives the same verdict.
Worked example: 3.2 mm/s RMS on a 55 kW motor bolted to a concrete floor sits in Group 2, where the boundaries are 1.4, 2.8 and 7.1. That reading is Zone C, so corrective work gets scheduled. Boundaries differ by machine group and foundation. Book a demo to see yours configured.
The zone tells you there is trouble. The spectrum tells you why
A rising broadband velocity is a trigger to look deeper, not a diagnosis. Three signatures cover most of what you will find.
Oxmaint holds the bearing detail against the asset, so defect frequencies are calculated rather than guessed at, and the trend is judged per machine. Book a demo to see a spectrum interpreted against an asset record.
Why a monthly route misses developing faults
Route-based collection gives you twelve data points a year on each machine. A bearing that begins to degrade in week two of a cycle has four weeks to progress before anybody looks.
Vibration change appears well before heat, and heat well before anything audible. The value of that lead time depends entirely on whether anyone is looking during it. Continuous collection turns twelve annual snapshots into a live trend, and the alert reaches a person rather than a spreadsheet.
Continuous monitoring does not replace a skilled analyst. It makes sure the analyst is looking at the right machine. Book a demo to compare your route data against a live trend.
Getting the measurement right
Inconsistent measurement makes trending worthless. Four rules cover most of it.
If vibration stays high after the machine reaches operating speed, that is a persistent fault rather than transient resonance. Book a demo to see how readings are captured and normalised.
Which assets to instrument first
Continuous sensors belong on the machines where a seizure stops production or the repair is measured in weeks. Everything else stays on route.
Machines above roughly 15 kW running between 120 and 30,000 rpm fall within the general industrial scope of the standard. Book a demo to prioritise your own asset list.
