Real-time frequency analyzers (RTAs) are extending the gains made toward improved machinery reliabilty through application of advanced vibration technology to high-speed, high capacity turbomachinery trains found in modern refineries and chemical plants. This article discusses an automated system for data analysis and maintenance of historical records in a dedicated minicomputer system for a periodic condition monitoring program undertaken for more than 100 major turbomachinery trains. Details of the RTA minicomputer system are given along with recommendations for practical use in refineries. The minicomputer automatically controls the real-time analyzer for vibration spectrum input. It has the capability to read a spectrum, then automatically erase, reset and restart the RTA in a second operation immediately following receipt of the data. Other peripheral devices include a digital to analog (D/A) converter for operating X-Y plotters or producing a CRT type display on a standard laboratory oscilloscope.
