Measurement and Diagnostic Techniques
FSI-VMDAcad. year: 2019/2020
The course represents some connection problems of measurement and technical diagnostics. Operation of modern machines and equipment are already is inconceivable without mastering systems of maintenance and diagnostics integrated them. Diagnostic technique is again able to perform its function without quality measuring techniques. The course therefore focuses on quality measurements, traceability of measuring instruments, their calibration and verification. In the following notes diagnostics in maintenance systems, especially the methods and means of basic two most common branches - vibrodiagnostics and thermodiagnostics. The whole addresses the issue in the context of the modern of the art including computer support. All is focused not only on conventional machines and equipment, but also to elements of control systems. Attention is also paid to the influence of environment on measurement and diagnostic equipment as well as monitoring parameters and its the subsequent correction.
Learning outcomes of the course unit
General overview of the means of measuring and diagnostic techniques. Detailed knowledge of the issues metrological traceability of instruments. The ability to design an appropriate measurement or diagnostic string for the application.
Basic knowledge from physics, mathematics, statistics and mechanics, introduction to the theory of the automatic control.
Recommended optional programme components
Recommended or required reading
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Course - unit credit: participation in laboratory exercises and presentation of measurement results. Resulting evaluation up to 30 points is included in the result of the examination, provided credit is to obtain at least 16 points. Exam: written test of all problems the subject (0 - 30 points), oral exam with written preparation (0 - 40 points). Total the student receives up to 100 points, condition passing of the exam at least 51 points. Classification: excellent (91-100 points), very good (81-90 points), good (71-80 points), satisfactory (61-70 points), sufficient (51-60 points), failed (0-50 points).
Language of instruction
Students will gain a more detailed overview of the field of metrology and technical diagnostics, as they are now used mainly in the everyday practice of automatic control systems and modern maintenance systems.
Specification of controlled education, way of implementation and compensation for absences
Attendance in laboratory excercies is monitored; one absence can be compensated for by attending a seminar with another group; next absence is compensated by solving an individual assignment.
