Abstract: Methods and systems for creating Campbell diagram displays for illustrating vibration characteristics of a moving apparatus, such as a rotary machine, are provided. Data, representing vibration amplitudes and frequencies are recorded against rotational speeds of an apparatus. The data is used to create waveforms representing the forward and/or reverse vibration frequencies of the apparatus. The waveforms in turn are used to create spectral line envelopes to provide enhanced two dimensional images indicating the amplitudes of the vibrations of the apparatus at particular rotational speeds. The spectral line envelopes may be empty, filled with one or more colors, or other illustration features to impart solidity to the envelopes to enhance visibility.

Abstract: Embodiments of methods and systems for monitoring of pumps are provided. According to one embodiment of the invention, there is disclosed a method for determining operating states of pumps. The method may include receiving, by a controller from a first sensor communicating with a first pump, a first vibration measurement.
