Do you know the source of a English language Video course with descriptional graphics & 3d images/animations covering Basics on rack based on line vibration monitoring system covering aspects like what is rotating machines shaft vibration , what different transducers are used to measure it , how is it used , how is it mounted and how a rack based on line vibration monitoring system works or just a video covering machine vibrations? Any info will help. Thanks jjamvant@yahoo.com
