Measurement Technology

Aim

To provide an overview of principles and methods of modern measurement technology. In the course the measurement of both electrical and non-electrical signals are treated. After the course the student should be able to:

• explain simple theories behind measurements of current and voltage of electrical cicuits, DC and AC, with multimeter and oscilloscope, and perform such measurements.
• explain the detection principle of perform measurements with some physical and chemical sensors
• explain components and functions in a computerized measurement system including; sensors, sensor interfaces, digitizing, data transmission, data analysis and data presentation
• implement numeric calculations and simulations related to the concepts in TFMT14
• demonstrate the ability to calculate the quantitative aspects related to the concepts in this course.
