This mode of analysis is like looking at instant replay from multiple camera angles, allowing the analyst to zoom in on a specific area of interest. Most machine malfunctions provide many clues prior to the “big event.” The key is to be able to recognize these clues as they occur.

A complete online monitoring solution can provide big returns, resulting in safe and optimized operations for this class of high-cost, high-speed machinery. Such a solution includes machinery protection monitoring, real-time predictive monitoring, and performance monitoring, all integrated with process control.
