In vibration measurements there are many techniques that may be used, but not all techniques are equally well suited for all purposes.
The main challenge for maintenance is to keep track of the current status of the machinery: Are they in good shape – or are they getting worn out, and if so:
- What is the lead-time to failure,
- what is the developing fault?
The main objective is: To detect if faults are present.
Therefore the scope is to utilize techniques that easily reveal if any of the possible faults on a machine is present – and developing.
- The CPB spectra with its wide frequency range and adequate resolution in any frequency range has proven to be the best tool for fault detection.
Selecting the proper technique for fault detection on rotating machinery makes it possible to detect them before the machine breaks down, thereby reducing financial losses, such as damaged equipment and production downtime.
