Set Vibration Alarm Levels without Guesswork

Setting vibration alarm levels to screen measurements made as part of a periodic monitoring project usually requires the assistance of an experienced vibration analyst or diagnostician. In this paper we show how to easily use the existing condition of the machines to establish these levels, and to use industry guidelines to qualify the results. This eliminates the guesswork and allows an inexperienced user to set meaningful levels, thus reducing the cost of implementing a Predictive Maintenance project. Two examples (overall vibration and spectrum enveloping) are shown to illustrate the methods.
