What does a higher amplitude in a vibration signal typically suggest?

A higher amplitude in a vibration signal is typically indicative of potential faults or imbalances within machinery. When a machine operates normally, the vibrations it generates are relatively low and consistent. However, when issues such as misalignment, unbalance, or mechanical wear occur, these can create irregular motion that translates into increased vibration amplitude.

This increased amplitude serves as a warning signal to maintenance personnel that further investigation is needed to diagnose the specific issue and prevent potential failure. Analyzing these amplitude changes is a crucial part of vibration analysis, allowing for predictive maintenance strategies to be employed, thereby reducing unplanned downtime and ensuring the smooth operation of machinery.

It’s essential to recognize that higher amplitude does not correlate with healthier machinery or higher efficiency—rather, it raises red flags that necessitate closer examination to maintain optimal performance.
