The benefits of vibration screening

Vibration can identify problems before other symptoms, including heat, sound, electrical consumption, and lubricant impurities. More than half of unplanned downtime is attributed to mechanical failures. While many things can impact the life of a machine, once the first signs of failure appear, a machine generally has only a matter of months before failing completely. Vibration testing provides a way to determine where the machine is on the failure curve and react appropriately.

Mechanical Vibration is a notoriously difficult subject matter to master. A quick glance at a textbook in the field shows that the advanced practitioner must master sophisticated concepts in mathematics and physics in order to accurately collect and interpret vibration data. This has caused a major problem for industrial plants—the benefits of a vibration testing program are well known, but far too many plants choose to avoid vibration testing because of the perceived complexity.
