Subject description
- Role of measurement systems in industrial processes (importance of proper measurement system design, influence of measurements to the final industrial product)
- Concept of measurement instrument and system (components, limitations, influence of the measurement system to the measured quantity)
- Analysis of time dependence of measurement system (size and type of sensor influence, delay in signal processing and presentation)
- Electronic measurements set up for measurement signal adaptation (bridges, amplifiers, filters)
- Techniques for decreasing measurement noise, grounding and shielding (proper grounding and guard usage in measuring small amplitude signals)
- Communication interfaces for measurement systems (computer and instrumentation)
- Software for measurements in industrial process systems
- Data acquisition (speed, parallel processing, influence of number of bits to the measurement accuracy, data acquisition of special signals)
- Basic concepts of virtual measurement systems (parts, requirements, interaction, integration)
The subject is taught in programs
Objectives and competences
The objective of the course Measurement systems in processes is linkage between measurement systems and industrial process systems related to regulation. The student acquired knowledge about time response and modelling of different measurement signals as well as understands procedures to choose adequate measurement instrumentation, which appropriate for the problem. In the scope of the course the grounding and shielding of electronic measurement systems is presented. The course in details presents interface bus for measurement systems automation, software requirements (data acquisition, data processing and data presentation) and virtual measurement systems.
Teaching and learning methods
In scope of the lectures the theoretical background on particular subjects related to measurement systems in industrial processes together with presentation of simple practical examples is given. A complete study material is available to the students.
Practical work is being performed in the laboratory environment, and is accomplished in steps acquainting students with the problem and process measurement system. Project group is consisted of two or three students who accomplish the measurements of process quantities. At the end of semester, students report on their results.
Expected study results
After successful completion of the course, students should be able to:
- Understand automatization of measurements in industrial processes
- Appropriately select and include modern measurements systems in regulation systems
- Design and implement communication interfaces
- Prepare and use appropriate software for automatization of measurements
