Abstract: There is one important term in the intersection of process measurement and industrial diagnostics: automatization of both processes by application of computers. This paper describes the role and significance of measurement for the choice of corresponding diagnostic method as well as for the final diagnostic efficiency. Assumption is that both, measurements and diagnosis, are the part of computer based system for automated control and regulation of industrial processes.
The fact is that the lack of a-priory diagnostic information is most often caused by poor or inadequate measurement data. New methods that must have been developed for global industrial diagnostics in such situations can also be successfully implemented in fault diagnostics of measurement instrumentation and systems. There is an obvious feedback from diagnostics to measurement. We can also speak about the impact of diagnostics improvement on improvement of measurement. New diagnostic methods developed for not well instrumented processes (mostly knowledge based methods), give especialy good results when implemented in systems with, from aspect of diagnosis, enough and adequate measurements. In this paper, we also give some of our results in field of diagnostics in order to support previous assertions
Key words: Industrial diagnostic, autoamtization, process measurement.
