Vibration measurement (Fingerprint)
Vibration measurements are an essential part of machine monitoring and diagnostics. The recording and evaluation of bearing and shaft vibrations is also known as fingerprint measurements. By analyzing frequency spectra, the origin of vibrations can be determined (root cause analysis). This is crucial in order to be able to rectify faults effectively.
Fingerprint measurements are often carried out before and after machine maintenance. A measurement before the maintenance serves as an inventory and allows actions to be implemented during the maintenance work. After the maintenance, measurements are used to check whether contractual limit values are being complied with and to ensure safe and unrestricted operation of the machines.
Our measurements are based on the ISO 20816-5 standard, which replaces the previous ISO 7919-5 and 10816-5 standards. This standard specifies the limit values for various vibration parameters to ensure a reliable assessment of machine conditions.
Features of the vibration measurements
- Acquisition of absolute bearing vibrations and analysis of their RMS values
- Acquisition of relative shaft vibrations and analysis of their peak-to-peak values
- Evaluation of frequency spectra and shaft orbits
- Understanding the origin of vibrations to determine measures
- Application to pumps, turbines and electromechanical drives of all kinds
It is also practical to carry out noise emission measurements in parallel with the vibration measurements.
