Vibration and temperature monitoring
A sensor on the machine measures vibration level (RMS velocity) and temperature continuously. The readings appear on the same monitoring screen as the oil data, in the same colours.

Oil and vibration together
Rising vibration is an important sign on its own. If particles or temperature in the oil rise in the same period, the warning gets stronger. The two readings confirm each other.
What it measures
- Vibration level, overall RMS velocity (mm/s)
- Bearing and housing temperature
- Trend and limit alarm
Reference standards
- For industrial machines such as motors, fans and compressors, the reference framework is ISO 20816-3. It replaced the old ISO 10816-3.
- For pumps we refer to ISO 10816-7. ISO 20816-3 excludes rotodynamic pumps. That is why pumps are assessed against a separate standard.
- Which standard applies depends on the machine type. The devices make no claim of compliance. The purpose is symptom detection and early warning.
Scope: The system does not carry out vibration spectrum (FFT) analysis. It does not identify which bearing or gear is failing. When vibration moves away from normal, it warns you to check the machine. For a detailed diagnosis you can work with a vibration analyst.
