Measurement uncertainty in vibromonitoring systems and diagnostics reliability evaluation

This paper analyses the influence of measurement uncertainty to the decision-making model, where possible values are distributed normally and are limited by predefined limit values. While analysing evaluation of uncertainty in vibration monitoring systems, the latter due to the features and nature of the measurement process are distinguished into two main types: permanently installed systems and periodical vibration monitoring systems. The uncertainty model for these two different monitoring systems is also provided.
