Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• the transducers typically encountered in engineering applications
• condition monitoring approaches, sensor types, sensor placement, data analysis
• the principles of instrumentation and measurement systems

Learning Outcomes

Having successfully completed this module you will be able to:

• C1/M1 Principles of cutting-edge sensors such as MEMS, acoustic emissions and ultrasonic techniques, as well as energy harvesting and wireless communication methods are introduced and applied in developing suitable condition monitoring systems for a given engineering/human setting. C2 Based on reliability analysis for the chosen system, units are selected for condition-based monitoring as the best maintenance strategy. C4/M4 As part of the group project students should find, critically review, and use literature to identify appropriate subsystems for condition monitoring. Also use literature identify sensing techniques and data processing methods for the application. C5/M5 To design a condition monitoring strategy, students have to consider the impact on the society, environment and economy when selecting maintenance strategies and techniques. C6 A condition monitoring system is a systems engineering approach, which integrates hardware, software, management and cost evaluation to reach the optimal solution. C7 The students should consider environmental and societal impact of condition monitoring strategies and minimise the adverse impacts with/without condition monitoring. C13/M13 For the condition monitoring strategy development, students must research and select appropriate sensors, power, and data acquisition devices and technology for the effective monitoring of a defined system. C16/M16 For the group project developing condition monitoring strategies, a group of 4-8 students work together, each leads/conducts one aspect of the system development. Project consultation with their project supervisors (module lecturers) leads to discussions on their progress and finalising their technique selections and cost evaluation. C17/M17 Presentations are requested during project consultation and students are requested to produce a project report providing an excellent description of their development to their ‘employers’ of the given tasks.
