Measuring systems are indispensable components for monitoring production processes, for the controlled operation of many systems and for checking the desired product quality in development processes. In all these cases, mechatronic components play a role both as operating components and as measurement objects to be checked. For this reason, this module teaches basic knowledge in order to be able to select and operate suitable measuring devices. In addition, experiments are carried out, evaluated and their results discussed. Examples of the measurement of non-electrical variables are primarily strain and acceleration in order to establish links to the technical mechanics modules. Finally, measuring chains are considered as examples of complete mechatronic systems.

1. Introduction: Aims, SI system, metrological institutions
2. Measuring uncertainties
3. Meausurement of electric signals
4. Computer-based measurements: Sampling and filtering
5. Examples for the measurement of non-electric quantities: strain gauges, accelerometers, temperature sensors

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• oral exam

The experimental work comprises 2 to 4 experiments.

Oral examination: see general section of the examination regulations

Experimental work: Experiment: approx. 2–4 experiments in total

Modules: Grundlagen Elektrotechnik, Festigkeitslehre und Werkstoffe, Mathematik

Students can quantitatively describe the behavior of measuring chains based on data sheets and have acquired important knowledge about the interaction of the components of a measuring system.

Students have deepened their knowledge of electrical and mechanical quantities by measuring them. They have thus deepened and repeated content from the basics of electrical engineering and strength of materials.

1. Students can select suitable components for measurements. They can operate common measuring devices. They can record and display measured values.
2. Students can evaluate measurement results and present them in a measurement protocol that ensures the reproducibility of the measurement.
3. Students have acquired increased interdisciplinary skills in describing and analyzing mechatronic systems using the example of measuring chains. They can therefore recognize connections between measurement technology, system theory and control engineering.

Through the joint preparation, implementation and evaluation of the laboratory experiments, the students have strengthened their ability to work together.
