Electrical System Instrumentation Technology IA4212

Learning outcome

After successfully completing the course, the candidate will have achieved the following learning outcomes defined in terms of knowledge, skills and general competence.


The candidate can:

  • Describe the function and operation of the main sensors and actuators (control devices) that are part of a process
  • Has knowledge regarding the prniciples of frequency regulation of electric motors and EMC.
  • Interpret signals based on their characteristics in time and frequency domains
  • Discuss the safety aspects of a measurement system, such as explosion protection, etc.
  • Describe digital modulation
  • Explain Fourier transform, z-transform and the design of digital filters


The candidate can:

  • Prepare the necessary basis for, program, implement and test a system that contains sensors and actuators
  • Select appropriate sensors, actuators and signal processing methods for a given process
  • Estimate the uncertainty of measurement data using statistical concepts such as standard deviation, average values, normal distribution, etc.
  • Assemble a measuring system focusing on its sensors, actuators and the processing of signals

General competence

The candidate:

  • Can describe the work done through a lab.journal
  • Is aware of the importance of safety in solution-oriented work

Course Description

The course is divided into two components: One component focuses on instrumentation technology, and the other focuses on digital signal processing.

The main topics in instrumentation technology are:

  • Measurement and instrumentation systems
  • Measurement systems and electrical output signals
  • Computer-based data acquisition
  • Basic statistical methods and uncertainty analysis
  • Selected methods
  • Dynamic measurement systems
  • Frequency regulation and EMC

The main topics in signal processing are:

  • Sampling theorem, folding
  • Modulation
  • Fourier series, frequency spectra, z-transform
  • Using filters

Teaching and Learning Methods

The learning outcomes are ensured through a combination of lectures, exercises and laboratry that include both hardware and software elements.

Assessment Methods

Written examination: 70%

Lab.journal 30 %

All laborator work, lab.journal, and the written examintaiton must be passed in order to obtain a final grade.

Individual grades (A – F).

Minor adjustments may occur during the academic year, subject to the decision of the Dean
