Entry knowledge

The student who enrolls this course should be able to explain the basics principles of sensors, understand the electronic circuits used in sensing and measurement technology, able to apply basic methods of electrical measurement (voltage, current, resistance, capacitance and inductance) and be able to assemble measuring chain with instruments as oscilloscope, function generator, DAQ cards for measuring of analog and digital signals and be able to prepare and use the LabVIEW developing tool. This course follows to courses in undergraduate studies BMVE and BSNI. Student should have such language skills to understand some educational materials in English.

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.


The goal of the course is to expand knowledge in technical diagnostics. Selected measurement methods and their application in practice will be presented, e.g. vibrodiagnostics, acoustic measurement, ultrasonic defectoscopy, thermovision diagnostics, etc. The aim is to give to students an overview and understanding of advanced diagnostic methods by using special sensors, analyzers and other advanced instruments.
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.
