Technology is great for solving problems, especially for complex problems when it’s couple with expertise. But in many cases, the technology and the expertise is separated geographically. Thankfully communications technologies continue to advance to bridge the distance between expert and problem. In a Power Engineering article, Remote Vibration Monitoring Keeps Power Plants Running at Full […]

Let’s continue our route-based maintenance video series with a look at diagnostics to detect misalignment issues on rotating machinery. In this 5:53 YouTube video, Misalignment Detection: Cross Channel Phase and Fault Frequencies, Emerson’s Drew Mackley demonstrates the analysis provided to data collected by portable vibration analyzers in route-based maintenance applications. He emphasizes the CSI 2140 […]

Alain Pellegrino, a predictive maintenance technician with Emerson’s local business partner Laurentide Controls, has a great article in ReliablePlant.com on resonance in plant equipment. The article, How to identify, correct a resonance condition, describes how resonance is a common cause in excessive machine vibration. Resonant frequencies are something most all engineers face whether it is […]
