Eligibility

General entry requirements for bachelor's level (first cycle)
Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.

Specific entry requirements

The same as for the programme that owns the course.
Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.

Course specific prerequisites

The first, second and third semester courses in Electrical Circuits, Electricity and electronics, Algebra, Mathematical Analysis, and Linear Systems.

Aim

The aim of the course is to introduce the students to modern electrical measurement systems, both for a theoretical and a practical point of view. 
The course gives the student an overall perspective on measurement systems, and provide a detailed analysis of some of their components.
The theoretical part of the course offers insights on the most common mathematical methods employed in measurement systems. The laboratory sessions give the students a practical knowledge on how to deal with sensors and modern measuring instruments.

Learning outcomes (after completion of the course the student should be able to)

Use electronic measurement instruments. (digital oscilloscopes, multimeters, etc...). Describe the structure of a measurement system and its basic blocks, namely sensors, filters, amplifiers, A/D converters. Explain the use of signal processing methods. Justify the need for shielding and grounding in measurement systems. Write basic LabVIEW programs. Develop awareness of academic honesty.

Content

In the course, we shall analyze a complete measurement system, from sensors to data processing. The following topics will be covered: resistive, capacitive, and inductive sensors; piezo-electric and piezo-resistive sensors, strain gauges and Wheatstonebridges. AC bridges, differential transformers, oscillators; instrumentation and charge amplifier; AD converters, filters; oscilloscope, frequency-analyzer; DFT, FFT; probes, bandwidth, rise-time, pulse reflection, impedance matching; uncertainty analysis: type-A and type-B uncertainty; error propagation; disturbances and interference coupling in measurement systems; EMC aspects in measurement systems; shielding and grounding; LabVIEW programming.

Organisation

The course is organized in lectures (2 or 3 per week), exercises sessions (1 per week) and four laboratory sessions.

Literature

Elektriska mätsystem och mätmetoder, Lars Bengtsson, Studentlitteratur

Examination including compulsory elements

Written exam on the theoretical part with grades U, 3, 4 and 5. The lab part gives a pass/fail grade. The final grade is based on the written exam.

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
