Educational Goals

The aim of the course is to provide the student with the necessary knowledge to understand the basic principles of operation of a measurement system and to perform measurements in which he will be able to determine their quality. Also to ensure the quality assurance of a product or service through quality control.
Knowledge: Introduction to the science of metrology with emphasis on electrical measurements. Ways to perform measurements of different quantities and calculations of these uncertainties. Principles of operation of analog, electronic, digital measuring instruments. Knowledge around sensor systems and their interconnection circuits (active passive) with recording instruments. Quality Control, Quality Assurance. Quality control tools.
Skills: Calculation of measurement uncertainties (direct-indirect). Error calculations using classical error theory. Operation of analog, electronic, digital. Measuring instruments with emphasis on electrical measurements. Implementation of sensor interface circuits with recorders. Use of quality control tools.
Competences: Implementation of measuring instrumentation by developing capabilities of measuring various physical quantities, calibrating and calculating uncertainties. Quality assurance of measurements and quality control of instruments and automation systems. Design of a product or service quality assurance system.

General Skills

Research, analysis and synthesis of data and information, using corresponding technologies, Adaptation to new situations, Independent work, Teamwork – distribution of responsibilities, Intellectual competences, Societal competence.

Teaching Methods

Lectures, Exercises, Online guidance, Projected Presentations, E-mail communication, Online Synchronous and Asynchronous Teaching Platform (moodle).

Students Evaluation

Assessment Language: English / Greek
The final grade of the course is formed by 70% by the grade of the theoretical part and by 30% by the grade of the laboratory part.
1. The grade of the theoretical part is formed by a written final examination.
The written final examination of the theoretical part may include:
Solving problems of application of the acquired knowledge, Short answer questions etc
2. The examination of the Laboratory Exercises is carried out insitu in order to evaluate laboratory skills and the theoretical knowledge that were obtained during the course teaching.
