DEVICE 03
SVM Vibration Sensor
Triaxial accelerometer in a metal body, mounted straight onto the bearing or motor housing. It measures vibration on the X, Y and Z axes, computes the frequency spectrum and tracks the tilt of the point. Every 15 minutes it sends the RMS over LoRa, and four times a day it records a full waveform capture for spectral analysis. The goal is not to grade the machine, it is to warn you when the machine changes relative to itself.

FROM VIBRATION TO CAUSE
The sensor measures. The platform says what it probably is.
Vibration becomes a product when the manager does not have to be a specialist to read it. DROME does not return a 0 to 100 score, it returns a state with a named cause and a deadline for action.
- 01
Paired capture
Four times a day the sensor records two captures, a fine one for resolution and a wide one for high-frequency content. In between, the RMS arrives every 15 minutes over LoRa and works as an event detector.
- 02
Spectrum of all three axes
The raw waveform is uploaded whole and the spectrum is computed on demand, never stored. The data stays reprocessable as the criteria evolve, with no need to rebuild history.
- 03
Baseline of the point itself
Each point becomes its own reference, with a median and a robust deviation per frequency band. Gain error, mounting resonance and noise floor cancel out in the ratio, which is why DROME uses neither ISO zones nor a generic score.
- 04
Verdict with gates before the index
Saturation, machine stopped, unstable regime and immature baseline are all checked before any index runs. A machine that is off does not become an alarm, it becomes a state. And the alarm only fires after confirmation across consecutive captures.
The band that rose tells you the type of problem
| Signature | Probable cause | What the team reads on screen |
|---|---|---|
| 1× rotation | Unbalance | The machine rotation is stronger than normal. It is usually built-up dirt, a bent blade or a missing part. |
| 2× rotation | Misalignment | A knock appeared every half turn. It is usually misalignment between motor and machine, or a worn coupling. |
| 1× with harmonics | Mechanical looseness | Knocks repeating several times per turn. It is usually a loose base, a slack bolt or a worn bearing housing. |
| 0.5× or subsynchronous | Rubbing or bearing clearance | A vibration slower than the rotation appeared. It is usually a part rubbing or a bearing with clearance. |
| Blade count × rotation | Blade pass | Blade pass is stronger. It is usually an obstruction, dirt on the rotor or a damaged blade. |
| Broadband, no peak | Cavitation, turbulence or friction | Overall noise rose with no dominant frequency. On a pump it is usually cavitation, otherwise friction. |
| 120 Hz | Electrical problem | Vibration appeared at the power line frequency. It is usually a motor problem, not a mechanical one. |
Without the machine rotation on record, the platform states the limitation instead of guessing a cause: it reports that the point changed relative to its own normal and stops there. Equipment with variable frequency drives, gearboxes, reciprocating compressors and many-bladed fans is out of range in this version. The warning horizon is weeks to days, not months.
