Condition-based maintenance (CBM) comprises two main parts – condition monitoring using the human senses or various technologies and, then taking preventive action if and when a fault is detected. It is often mistakenly considered to be a form of Preventive Maintenance. In fact, using CBM there is no prevention of any failures at all, there is only the identification of failures that have already begun to occur, but have not yet progressed so far as to be problematic. This course introduces basic CBM concepts, why we use it, how we use it, and how often we should use it, as well as the difference between CBM and preventive maintenance. The various technologies applied in condition monitoring: human senses, vibrations, ultrasound, oil analysis, infrared and non-destructive testing are all introduced. The impact of the Industrial Internet of Things, Machine Learning and Artificial Intelligence is also presented. The student should come away with a good understanding of the technologies available for use and enough information to make informed decisions on what technologies are most applicable in a given situation. 0.4 CEU awarded.
