Osilera Monitor · continuous vibration monitoring

Know which machine needs you before it stops the line.

A wireless sensor on every motor, pump, fan, gearbox and roll. It measures vibration, speed and temperature around the clock, and gives your team one clear status per machine: Normal, Watch, Act.

  • No tachometer
  • ISO 20816
  • Inverter motors
  • Wireless mesh
  • 4–6 year battery

The challenge

A plant runs on hundreds of machines, and most are checked once a month at best.

Motors, pumps, fans and gearboxes fail in familiar ways: a bearing wears, a rotor goes out of balance, a coupling drifts, a gear tooth chips. Each fault starts small and grows over weeks. A monthly round catches it only if someone is there on the right day.

Inverter motors make it harder. When speed changes every hour, a fixed vibration limit is too tight at full speed and blind at low speed. And many critical machines sit behind guards, on high platforms or in hot, wet areas where cabled systems cost too much.

No tachometer

Speed comes from the sensor itself. No PLC signal, no cabling.

Wireless mesh

Sensors report to a plant gateway. Mounted by stud, adhesive or magnet; no calibration.

4–6 year battery

Depending on sensor model and battery option. No wiring to install.

Managed remotely

Settings and firmware updates reach the sensor over the air.

Early warning

A failing bearing gives early signs long before the machine shakes.

Most monitoring watches one number: ISO vibration velocity. It barely moves until the damage has spread. Osilera also follows the high-frequency bearing band, where a roughening race shows weeks earlier. That gives you time to order the part and plan the stop.

Typical progression. A falling impact index with a rising bearing band is a late-stage sign, not a recovery.

Velocity

ISO 20816 figure on all three axes.

Speed and orders

Shaft speed, plus vibration at each multiple of it.

Bearing band

Above 2 kHz, with an impact index and envelope spectrum.

Temperature

Warning and alarm levels set per machine.

Built for inverter motors

Speed changes. Your comparison still holds.

When speed changes, every vibration line moves with it, and a fixed limit either misses the fault or raises false alarms. Osilera measures the shaft speed with every reading, from 70 to 3,000 r/min, and expresses vibration as multiples of that speed, called orders. Unbalance stays at 1X and misalignment at 2X, whatever the machine is doing.

Motors

Balance, alignment, bearings and temperature.

Pumps

Vane pass and flow noise.

Fans

Blade pass, and the build-up that unbalances a fan.

Process rolls

Slow rolls compared with their neighbours on the line. Rolls and lines

From reading to action

A status per machine, and what to do about it.

Each machine is graded against the ISO 20816 zones for its class and against its own history at the same speed. Your team sees Normal, Watch or Act in Osilera Web. The detail is there for the analyst who needs it.

Osilera shows which machine is changing, in which fault family and how fast. Your maintenance experts make the repair decision, and our vibration specialists are there when you need them.
