Vibration 101

What is vibration data? Why is it important?  6, 12 & 18 as measured in "g" or "G". An acceleration equal to the acceleration of gravity, 980.665 centimeter-second-squared, approximately 32.2 feet per second per second at sea level; used as a unit of stress measurement for machinery components undergoing acceleration.  Our thresholds of 6, 12 & 18 Gs are based on decades of reliability around rotating equipment such as pumps, fans and motors.  Rules-based approaches and AI can integrate these signals into inspect and lubricate to imminent problem and recommended actions.  

Overall Vibration is a lagging indicator, great for showing imbalance, looseness and misalignment but not a leading indicator for predictive intelligence.The Vibration Ultrasonic Spectrum (which is typically a waveform) is a very early indicator, indicating bearing faults such as inner race or outer race defects, lubrication faults and cavitation, leading to actions that can remedy the problem in advance and schedule accordingly to prevent unplanned downtime.

Both are needed for a holistic view, but overall vibration utilizing simplistic accelerometers is not enough for predictive intelligence in rotating equipment with roller element bearings.  In order to schedule maintenance to avoid costly unplanned downtime or breakdowns in equipment, you must think of the time that production and maintenance professionals need to react, and that is why our system is designed around real-world use cases below.
