Online Training - Machinery Diagnostics

DESCRIPTION People will learn to read and interpret vibration data plots and to recognize common rotating machinery malfunctions. Students will develop these abilities by gaining understanding of the fundamental principles that govern rotating machinery vibration. Application of these principles will enable students to understand the basic root causes of machinery malfunctions and their corrective actions. Multiple hands-on labs will give students opportunity to practice their skills using real machine case histories and lab stations equipped with rotor kits and advanced diagnostic instruments. See Outline for more.
