Course detail

Electronic Measurement Systems

FEKT-MPC-EMSAcad. year: 2024/2025

The course deals with technical resources for measurement automation. Basic solutions for measurement systems’ design assembled from both specialized instrumentation and universal components is explained. Attention is especially focused on designing a system that meets the specified requirements, selection of suitable components and software implementation issues.

Entry knowledge

Knowledge in the Bachelor's degree level and basic usage of the development environment NI LabVIEW is required.

Rules for evaluation and completion of the course

Up to 30 points for laboratory exercises:
- theoretical test - up to 8 points (EEN, EKT, KAM)
- 2 projects (EEN, EKT) or 3 practical tests (KAM) - up to 22 points.
Credit is given for all tests or projects submissions and gain of minimal 10 points from all parts.
Up to 70 points for the final written exam (theoretical part - 30 points, practical problems - 40 points, gain for succesful exam of both parts is 50% of points).
Participation in laboratory exercises is not mandatory excluding tests. Assessment is based on submission of projects or tests in the selected exercises during the semester.

Aims

The course goal is to familiarize students with the process of design and implementation of measurement systems. Student will learn to work with common measurement systems and understand the problems of measurement automation. Student is able to choose an appropriate concept of measurement system, assemble it and determine its measurement uncertainty. He knows the way of description of the general properties and structure of the measurement system.
Graduate student knows:
- terminology of measurement systems,
- basic modular systems for automation of measurement and corresponding standards.
Graduate student can:
- perform theoretical design of the measurement system,
- determine sources of uncertainty in the measurement system,
- create simple measurement system including software implementation (NI LabVIEW),
- determine requirements for the robustness of the system and its operation.
