2.4 Common Vibration Severity Charts and Tables As mentioned above, vibration amplitude (displacement, velocity or accelera tion) is a measure of the severity of the defect in a machine.
Vibration magnitudes should be above these levels for about 10 s before an Alarm or Trip is released, to avoid false alarms and trips. For filtered levels see the standard. 1.5.1. Application of this Standard This is the latest part of this standard whose development was led by User Industries. It can be
Vibration measurement and analysis is a main method of condition monitoring applicable to rotating machines in general. The amount of vibration depends on: The exciting force. How close the frequency of this exciting force is to structural resonances or their multiples (harmonics). The restraints that pump structure imposes to vibration.
