Osilera Survey · mobile vibration analysis app

Measure once. Know what is wrong and what to do next.

A sensor and your phone or tablet become a vibration analyst you can carry. Measure any machine and get its ISO grade, the fault and the next step, right at the machine.

Osilera Survey sensor, aluminium body with the cyan Survey label

For maintenance managers

A vibration analyst in every technician's pocket.

Most machines never get a proper vibration check. The data collector is booked, the consultant is expensive, and a simple meter gives a number without a reason. Osilera Survey gives your team a full analyser, the ISO limits and an expert's reasoning, on the phone or tablet they already carry.

Answers on the spot

Unbalance or resonance? Mains or inverter? Which bearing? Your team knows before they leave the machine.

Time to plan

Bearing faults are named while the overall level is still flat, so the repair goes into a planned stop.

Records that stand up

Every reading is ISO-graded and saved with its evidence, ready for the maintenance file or an audit.

Mount

Fix the sensor to the bearing housing with a stud, adhesive pad or magnet. The app checks the mounting as you go. Use the stud or pad for bearing diagnosis.

Capture

Press one button. A full three-axis reading takes seconds. A 10-second capture adds slip and load.

Understand

The reading opens on the answer: ISO zone, named findings, what has changed and what to do next.

Inside the app

Define it once. Press one button. Read the answer.

Machine definition in the Survey app — **The app shows what each detail unlocks.** Enter the machine once. Each field switches on more checks.

The capture screen — **One button for the best reading.** Slip, tap test and other capture types are one tap away.

An envelope spectrum with a bearing defect line — **A bearing defect on screen.** One clear peak at the bearing's defect frequency, with its harmonic beside it.

The reading's verdict: bearing condition confirmed, with the next step — **The reading opens on its answer.** The fault, how sure the app is, and what to do next come first. Evidence, spectra and trend sit one tap behind.

What sets it apart

Six things a handheld usually cannot do.

Speed with no tachometer

The app finds the shaft speed from the sensor itself. Nothing to wire, aim or stick on.

Separates faults that sit close together

Fine 0.33 Hz lines keep a mechanical fault apart from an electrical one less than 2 Hz away.

Tap test for resonance

Tap the machine to see whether it needs balancing or has a resonance, before you pay for a balancing job.

Slip and load, no clamp

Slip, supply type and load band from one capture. No panel access, no electrician.

It tells you when it can't be sure

If the evidence is not enough, the app says so and tells you exactly what to measure next.

Spots what has changed

New or growing vibration lines are compared with the machine's reference and reported in plain words.

±0.5 %Amplitude accuracyAgainst a reference calibrator.

< 1 %ISO velocity accuracyAgainst a reference calibrator.

0.33 HzLine spacingAbout 6,500 usable lines on the long record.

±0.14 %Slip from one captureWith no current clamp.

What it finds

A diagnosis you can act on.

Every line in the spectrum is traced to a cause: the shaft, a bearing, the supply, a gear. The app follows the ISO 13373-3 order of work: severity, diagnosis, further test, action.

Fault	What you get
Unbalance	Severity graded, and growth caught even inside zone A.
Bearings	Outer and inner race named from the bearing's own frequencies; ball and cage damage detected early.
Broken rotor bars	Found from one capture, with severity growing with each broken bar.
Electrical and slip	Supply, slip, load band and mains or inverter; electrical lines kept apart from mechanical ones.
Resonance	Tap test per direction, and resonant readings kept out of trends.
Pumps	Cavitation screen and blade-pass check, with a prompt to check the suction.
Misalignment	Reported with the checks that pin it down.
Gears, belts, chains	Each stage and rate worked out from the machine definition, then flagged for inspection when it changes.

Five clear answers

ConfirmedIndependent signs agree.

IndicatedOne strong sign; the confirming test is named.

PossibleWorth a look; the app says what would settle it.

ClearFully checked, nothing found.

Not assessedThis reading can't answer; the fix is given.

Survey + Web

Every reading lands on the same point as the sensors.

Readings taken with the app are sent from the phone or tablet to Osilera Web, onto the same machine and measuring point. There they sit next to the Monitor sensor's data, and an analyst can compare a Survey spectrum with the sensor's own.
