Course detail
Measuring Techniques for Technical Diagnostics
FEKT-MPC-MTDAcad. year: 2023/2024
The course deals with methods, sensors and instrumentation for measuring noise, vibration, ultrasound and thermovision diagnostics. Students will learn the technique of vibration measurement, noise and speed measurement as well as the basics of spectral analysis, bearings fault diagnosis, balancing and diagnostics of rotating machines. Other topics will be basics of modal analysis, calibration of sensors, use of thermal cameras and ultrasonic diagnostic equipment in industrial applications.

Rules for evaluation and completion of the course
Laboratory exercises 0 - 30 points. The condition for obtaining credit is participation in laboratory exercises and preparation of technical reports from laboratory measurements - 6 laboratory tasks (6 x 5 points).
The final exam is aimed at verifying the knowledge (orientation) of the completed course. It has a mandatory written and an optional oral part. The written part of the final exam is 0 - 60 points, minimum 25 points. The oral part of the final examination 0 - 10 points.
Definition of controlled education will be established by announcement published by course supervisor every year. Mandatory participation in laboratory exercises, in case of absence the exercise work can be supplemented with alternative exercise in same week or with a self-study of additional literature.
Aims
The student will be able to describe the types and methods of technical diagnostics, explain a diagnostic problem, choose the appropriate measurement method, select right sensors and measuring instruments for the specific application. Student will be able to specify parts of measuring chain to realize measurements and evaluate the measured data.
