Application Of Spectrum Analysis To Onstream Condition Monitoring And Malfunction Diagnosis Of Process Machinery

Abstract

Recent experiences with frequency spectrum analysis for onstream evaluation of mechanical performance are reviewed from a user's standpoint. Current practices of transducer selection and positioning, data acquisition and interpretation are outlined as applied to both predictive and malfunction analysis work. Particular emphasis is placed on assessing the efficacy of these techniques by indepth reviews of case histories from recent field applications.
