06 Oct 2011Effective Use of Statistical Models to Establish and Update Vibration Alarm Levels
This paper will discuss various statistical techniques for automatic determination of alarm limits in vibration analysis. The goal is to determine the method which yields the highest level of diagnostic accuracy in the most automated fashion while producing the minimum number of "false alarms". Several approaches can be taken to this task including: 1) statistical calculation of alarm limits for user-definable frequency bands, 2) statistical generation of external envelope alarm limits based on a single reference spectrum, 3) statistical generation of external envelope alarm limits based on a composite spectrum representing normal machine operation, and 4) variable state statistical analysis (for machines with variations in speed, load, etc.). This paper will contrast the performance for each type of alarm limit based on an actual machine study.
06 Oct 2011Vibration Analysis of Vibrating Screens
Vibration analysis is a very powerful and cost effective tool. Put to good use, it can help save thousands of pounds in unplanned downtime and unnecessary maintenance activities. However, there is a piece of equipment that escapes the more traditional analysts, the vibrating screen. They are normally passed over on the initial sight assessment due to their large and seemingly violent motion. However, the vibration analyzer is capable of providing a wealth of data that can help both maintenance and production get full utilization out of their screen.
06 Oct 2011What's New in AMS Suite: Machinery Health Manager
AMS Machinery Manager is CSI's 32-bit Windows condition monitoring software that replaces MasterTrend. Having the technical hardware tools to monitor machines is important and necessary, but without a powerful software system to set these equipment up and also to store and analyze the data collected you would be left with a half baked cake in implementing a successful RBM program
