New Vibration Measurement Application Note helps with Complicated Metrology
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.
Don Martin, president of Lion Precision explains that a typical vibration meter will use accelerometers. When high frequency forces are the concern, this is an appropriate choice. Many people are using these devices to determine lower frequency displacement and just not getting very precise results, but because its a vibration meter they assume its the right tool and dont realize there are better methods.
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 application note is intended for anyone needing to better understand and measure vibration, adds Lion Precisions communication manager, Mark Kretschmar. It is not primarily about Lion Precision products. He explains that Lion Precision is developing a Technical Library of application notes and TechNotes to help engineers and metrologists make more precise measurements whatever product or technology they are using. The application note even details how best to mount a sensor in a vibrating environment, no matter what type or brand of sensor it is.
The Vibration Measurement Application Note is available as a web page and PDF document in the Technical Library section of the Lion Precision web site at www.lionprecision.com. Or a direct url is here:
In 1958, Lion Precision was the first company to provide capacitive displacement sensors to industry. The company has expanded its product offering to include eddy-current displacement sensors and some application specific sensors for the machine tool, packaging and PCB industries. The company is focused on assisting users in sensor implementation by providing expert guidance and optimized systems including custom designs.
Lion Precision, an IBS Precision Engineering partner, sells the Triskelion in the United States. The company was established in 1958 and pioneered commercially available noncontact sensing systems. The company provides high-performance capacitive and eddy-current displacement sensors for industries such as machine tool, semiconductor, disk drive, automotive, packaging, and university and national laboratory research.
