Part I Course Duration : One Semester Credit Units: 3 Level: B3 Medium of Instruction: English Prerequisite(s) : MEEM2029 (offered until Semester A 2011/12) / MBE2029 Electrical and Electronic Principles I or equivalent, and MEEM2003 (offered until Semester A 2011/12) / MBE2003 Mechanics or equivalent Precursors(s) : Nil Equivalent Course(s) : MEEM3061 Instrumentation and Testing Technologies Exclusive Course(s) : Nil Note: Students may repeat a course, or an equivalent course, to improve course grade only if the previous course grade obtained is D or below. Part II Course Aims: The aim of this course is to introduce testing technologies relevant to the design and imple-mentation of product testing systems, with emphasis in the toys and electric appliance manufacturing industries. Course Intended Learning Outcomes (CILOs) Upon successful completion of this course, students should be able to: No. CILOs Weighting* (if applicable) 1. Outline fundamental concepts of measurement and basic principles of instrument classification and static and dynamic characteristics of instruments 2 2. Clarify the use of transducers for converting physical variables to useful forms for measurement 2 3. Develop tests for measuring physical parameters such as for mechanical and electrical parameters 3 4. Familiarise with fixtures and elements of automation for the development of product testing systems 2 5. Design conformity tests with reference to commercial product standards 2 *Weighting ranging from 1,2,3 to indicate the relative level of importance in an ascending order. Teaching and learning Activities (TLAs) Activity Type: Timetabled Activity (Hours per week) Lecture/Tutorial/Laboratory Mix: Lecture (2); Laboratory (1) TLAs Large Class Activities Practical Work Total (hrs) CILO 1 3 3 6 CILO 2 3 6 9 CILO 3 8 6 14 CILO 4 4 3 7 CILO 5 6* 3* 9 Total (hrs) 24 21 45 Large class activities. There will be 24 hours of lectures. The lectures cover measurement concept fundamentals, basic knowledge and applications of transducers, methods for measuring physical parameters (such as motion, power, temperature, acoustics, and electrical quantities), elements and design of testing systems, product standards and conformity testing. Practical work. Practical experience is an important part of this course. There will be about 6 three-hours laboratory sessions. Possible topics to be included are evaluation of errors and uncertainties, response characteristics of transducers / instruments, application of transducers (such as thermisters, strain gages), tests of physical parameters, pneumatics, PLC programming, computer-based data logging, etc. Industrial experience of product testing will also be pursued through site visits or workshop in collaboration with local product testing laboratories. * May consider collaboration with commerical product testing laboratories or product testing professionals, such as site visits to laboratories, workshop or guest presentations. Assessment Tasks/Activities(ATs) ATs Examination (2 hrs) Project Laboratory Report / Participation Total (%) CILO 1 10 - 5 15 CILO 2 10 2 10 22 CILO 3 20 2 10 32 CILO 4 10 2 5 17 CILO 5 - 14 - 14 Total (%) 50 20 30 100 There will be a group project. Standards will be specified to students. Students will identify a product. They will then design suitable testing systems and develop testing procedures for conformity testing. System design should eccompass identifying test requirements, selection of testing techniques, equipment and methods, design of testing setup, and setting criteria for product conformity. For a student to pass the course, at least 30% of the maximum mark for the examination should be obtained. Grading of Student Achievement : Examination, project and laboratory reports will be numerically-marked.
