Vibration and its measurement are filled with vagaries that can make a seemingly simple task a daunting one instead. A new Vibration Measurement Application Note from Lion Precision helps bring some clarity and definition to the issue. The basic problem stems from the fact that there are myriad methods and tools to measure vibration, and each of these may have different measurement units and confounding factors so the results may differ greatly.
The vibration measurement application note helps the reader determine which tool is best for a specific application. Some tools, like accelerometers, are well-suited for applications in which the forces and strains resulting from vibration are the primary concern. Displacement sensors are better for applications in which the actual ‘travel’ of the vibrating part is the important consideration. These devices are affected very differently by the frequencies of the vibration – a fact which must be considered.
In addition to the vibration sensor technology, the measurement result can be expressed in many different ways such as a single ‘total vibration’ value, a frequency spectrum or real-time instantaneous measurements. And each of these can be expressed in RMS, peak, or real-time values. The Vibration Measurement Application Note-Full Report.
