Course description:

Course objectives: Aims: To give students a basic knowledge about the sensors of more relevant physical quantities and familiarising them with their operating principles. To prepare students for selection of sensors appropriate for specific measurement environments, and for understanding of catalogue data. Enrolment requirements and required entry competences for the course: Previously attended any course belonging to the "Electrical Engineering"group, such as: "Electrical engineering" "Electronics" "Electrical engineering and electrical machines" Student responsibilities: Teaching activities consist of lectures and auditory and laboratory exercises, wherein student attendance is regularly checked. A minimum attendance rate of 70% is strictly enforced. Absence from laboratory exercises needs to be notified in advance. The missing laboratory time can be redeemed either through oral examination or by offering to attend the laboratory exercise with another teaching group. Unethical behavior during preparation of the written assignment (equivalent to written exam) is not tolerated. Grading and evaluation of student work over the course of instruction and at a final exam: Successful completion of written assignment is equivalent to a successful written exam. Maximum proportions of individual exam components: Written assignment 50% Oral exam 50% Grading system: 5 87% or more, 4 76% to 87%, 3 65% to 76%, 2 50% 65%, 1 below 49% Methods of monitoring quality that ensure acquisition of exit competences: At the beginning of each lecture or exercise, a brief recapitulation of previously presented subject matter is performed (up to 5 minutes). During the lectures/excercise interactive teaching process is established. Afterwards, students are pointed towards further broadening the subject matter via appropriate literature. The subject matter for the next lecture/exercise is announced and additional teaching materials are offered. Consultations, either in person or via email correspondence, are also encouraged. During the semester, students are given the opportunity to actively participate in practical laboratory exercises which further illustrate the subject matter presented at lectures and auditory exercises. Interaction with students is important for teaching process evaluation. Upon successful completion of the course, students will be able to (learning outcomes): analyze the stationary and dynamic behavior of sensors, transducers and measurement chains envision the process of calibration of transducer system plan the measurement system noise suppression measures select appropriate sensor systems for control and diagnostics of mechatronic and robotics systems plan the measurement implementation in industrial envirnoment validate the performance of different sensor systems Lectures 1.
