Evaluating a Fan and VFD System with Motor Current Signature Analysis
Both Electrical and Current Signature Analysis (ESA/MCSA) can be used to evaluate conditions of a system and assist in preemptively mitigating defects while optimizing system efficiency based on their specific functions. In the case of this article we will focus on a simple single-phase MCSA tester and a fan system with a variable frequency drive that had a synchronous belt installed...

Success Story: SONOTEC X PD Energy GmbH
Ultrasound is the technology for the first step in damage detection and has the advantage over other methods in that it can be used at all bearing speeds. Even with extremely low-speed bearings, damage can be detected at the earliest possible stage.

Avoiding Unplanned Downtime: Online Monitor of Critical Bearings
Keeping a close eye on the condition of critical equipment is fundamental in any industrial facility. When critical bearings fail, it almost always leads to unplanned downtime and interrupted production process, costing companies thousands in production loses. In this case study we will look at how an online monitoring solution using ultrasonic sensors was able to detect an issue on a critical bearing before it turned into a big problem.
