Vibration Instrument Class Verification
Verify if your vibration measurement instrument meets ISO 2954 class requirements. Enter instrument specifications to check compliance with frequency range, accuracy, and filter requirements.
Compliance Check
ISO 2954 Key Requirements
| Parameter | Requirement |
|---|---|
| Frequency range | 10 Hz to 1000 Hz (velocity) |
| Flatness in band | ±5% (±0.5 dB) |
| Accuracy at reference | ±5% of reading |
| Overall accuracy | ±10% including environment |
| Filter roll-off | ≥ −12 dB/octave |
| Linearity | ±5% of full scale |
| Measured quantity | Velocity, RMS, broadband |
Frequency Response Requirement
Given: Range 10–1000 Hz, accuracy ±5%, roll-off −12 dB/oct, linearity ±3%
Frequency: 10 ≤ 10 Hz ✓, 1000 ≥ 1000 Hz ✓
Accuracy: 5% ≤ 5% ✓
Roll-off: 12 ≥ 12 dB/oct ✓
Linearity: 3% ≤ 5% ✓
Result: COMPLIANT
⚠️ Note: ISO 2954 compliance is the minimum requirement for vibration severity measurements per ISO 10816 / ISO 20816. Modern analyzers typically exceed these specifications significantly.
ISO 2954 compliant vibration meters and analyzers. Calibrated measurement instruments for industrial use. Used in 50+ countries.
Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
