Abstract

Technologies are generally described for a vibration band alarm configuration tool to facilitate efficient and reliable setting configuration by displaying data and analyses pertaining to the data produced by a vibration transducer attached to a rotating machine and thereby reduces needed knowledge of machinery and vibration analysis. Various parameters and data sets may be calculated from the time domain waveform and displayed with collected data to simplify the recognition of features that represent system components and anomalies pertinent to the health of the rotating machine such as a pump assembly. Manually manipulatable controls on a graphic user interface may allow a user to set alarm bands and thresholds. Suggestions based on physical and/or statistical models, as well as, machine-specific historic data may be presented as well.
