Summary of Content

This module aims to provide an understanding of both Mechanical and Electrical Condition monitoring and associated instrumentation requirements for successful condition monitoring. The main focus in Mechanical Condition Monitoring is vibration monitoring since this is the most popular method of determining the condition and diagnosing faults in rotational machines, although other techniques used in condition monitoring are also covered. The module also includes a review of relevant sensors, data acquisition/ analysis and the essential instrumentation required in condition monitoring. Electrical Condition Monitoring will develop an understanding of the need for, and challenges in, measuring electrical signals in machinery. The application of standard and non-standard electrical condition monitoring systems to a range of electrical plant will be explained. The students learn to use condition monitoring tools and then to evaluate the data provided by them.


The teaching syllabus will cover the following areas. Mechanical Condition Monitoring: Introduction to condition monitoring: Maintenance strategies, concept of condition monitoring and main methods involved- vibration monitoring, visual / performance monitoring, Oil & debris analysis etc. Vibration Monitoring : Basic vibration theory, vibration measurement and analysis, machine vibration; Rotational machine faults and vibration characteristics. Applications of vibration monitoring to rotating machines. Vibration monitoring in practice - overall vibration monitoring and experience based spectrum analysis to detect machine condition and faults in bearings and gears. Current diagnostic techniques/tools commercially available. Thermal Monitoring :Introduction to thermal monitoring; thermal monitoring techniques, application of thermal monitoring to manufacturing processes. Thermal imaging camera, and its application as a condition monitoring tool. Lubricant analysis/monitoring : Introduction to tribology - lubricant types and their properties. Introduction to wear debris monitoring; collecting and quantifying wear debris; wear debris and oil analysis in practice. Sensors for condition monitoring: Accelerometers, strain gauges, eddy current probes and LVDT for measurement of displacement, velocity and acceleration. Lock in amplifier for signal conditioning. Thermocouples, thermistors, resistance thermometers and junction semiconductor devices for temperature measurement. Radiation pyrometers for temperature measurement, Thermal imaging devices. Data acquisition and Analysis for condition monitoring: Fourier analysis and FFT, Sampling, Shannon's theorem, Analogue to digital conversion. Static characteristics of signals including mean, standard deviation, skewness and kurtosis, probability density function, power spectral density and autocorrelation. Electrical Condition Monitoring: Overview of electrical plant and how the interaction of inherent stresses causes degradation of plant Components and affects equipment operation; Electrical contact methods for assessing electrical plant condition; Acoustic measurement of electrical plant condition; RF/UHF assessment of electrical plant condition; Chemical methods of assessing electrical plant condition;

Teaching / Learning Strategy

Full time This module will be taught by lectures, laboratory demonstrations and case studies. The laboratory demonstration will cover a whole range of equipment and the students should be able to correlate the test results with the taught material, thus enhancing student appreciation. Appropriate coursework in related areas should develop analytical ability and practical application of engineering tools, thus further consolidate student's understanding on the subject Part time Part time students will attend the full time week and undertake the lectures and practical demonstrations along with the full time students. They will be provided with a study pack which will cover the material. Tutors will be available for consultation via GCULearn, e-mail and telephone. Distance Learning: Students will be provided with a study pack which will cover the syllabus material. The module content will be delivered through a combination of notes, tutorials and practical exercises. The Study pack will also contain additional support material for the practical element for example sample data and links to appropriate websites. Tutors will be available for consultation via GCULearn e-mail and telephone.
