Diagnostic vibration data collector and analyzer

摘要

A portable data collector/analyzer comprises a transducer for being attached to a machine in order to produce an output signal indicative of vibration of this particular machine; circuitry for conditioning the output signal and converting it to vibration data; and a memory for storing the vibration data. It further has an expert system for performing advanced vibration data analysis of the vibration data stored in the memory based upon: (i) vibration test and analysis guide information; (ii) full average spectra files; (iii) prepared refined rules based on past experience of major machine groups; and (iv) a specific knowledge of the idiosyncrasy of the particular machine.
