What is one of the pros of using overall RMS levels?

Using overall RMS (Root Mean Square) levels as a vibration analysis metric offers a significant advantage in that they are easy to collect. This ease of collection stems from several factors. First, RMS levels simplify the process of obtaining a single value that represents the energy content of vibrations over a defined time period, rather than requiring extensive data analysis or interpretation. This singular value allows for quick assessments of machinery or structures without the need for complex calculations or the handling of large data sets.

In addition, collecting RMS levels typically requires straightforward instrumentation, such as basic accelerometers or vibration measurement devices that do not necessitate elaborate setup or specialized training. This accessibility means that operators can gather important vibration data more frequently, aiding in routine monitoring and maintenance efforts.

While other choices may present certain benefits in specific contexts, the key benefit of ease of collection makes RMS levels particularly appealing for general monitoring and initial assessment in many vibration analysis scenarios.
