OCTAVE BAND REVISITED: MACHINE CONDITION MONITORING USING OCTAVE BAND DATA COLLECTORS

In the field of machine condition monitoring, the range of instrumentation available to the millwrights and maintenance personnel in the primary resource and process industries has become increasingly complex, and techniques more sophisticated. This is due in part to developments in the electronics and computer industries, but also to companies' becoming aware that an improved maintenance philosophy manifests itself in the form of increased productivity and profitability. This paper describes an approach, pioneered initially by the Canadian Navy but modified to suit the needs of industry, that has proved effective in a number of primary resource and process companies located in Quebec, Canada. The evolution of the instrumentation is described from an historical perspective and the technical merits of two types of measurement, constant percentages bandwidth (CPB) and fast Fourier transform (FFT), are compared and contrasted in order to develop the rationale for the approach. A number of case histories and examples are described to support the techniques proposed.
