Predictive Maintenance

Measurement and vibration analysis to control machines health status

Any machine, during its usage, produces vibrations and sounds. When these vibrations are intensified abnormally, it is very likely that the machine is about to break down. Condition monitoring and preventive maintenance techniques are based on this principle. Depending on the type of machinery and rated power only some levels of vibration are acceptable. These values are often defined by the manufacturers based on international standards such as the ISO 10816 series. A change in the vibration level generated by the machine, even if it is below defined limits, is often indicative of a malfunction. This type of evaluation goes under the name of “first level”. We know that the machine has a problem, but we do not know which one. However, vibrational analysis, through more advanced analysis in the frequency domain provides information on the type of failure becoming an excellent diagnostic tool.
