Abstract
A system and method of monitoring vibrations, in a machine having a rotating element, where composite vibration signals are measured and filtered into discreet vector components associated with machine operating frequency. The filtered vectors are then evaluated to obtain a mean and standard deviation, whereupon a further value is obtained and compared to the prior values. Trip conditions may be set to initiate certain actions based on the meeting of the conditions. Additional data related to operating conditions of the machine may be analyzed in conjunction with the vibration data to be considered as providing a cause for vibration anomalies that may be observed. The operating, conditions of the machine may be displayed on a computer display in association with the discreet vector components, for example in a second level folder to the first level folder of the discreet vector components.
