Electrical sensors (3cr)

Objective

After completing the course, the student will be able to identify the basic sensors used in machine automation and understand their operating principles, electrical and mechanical characteristics, and performance parameters. The student is able to select an appropriate sensor for a given detection or measurement task in a way that supports sustainable development – for example, by ensuring that the sensor has sufficient service life and is suitable for energy-efficient operation. The student recognizes sensor electrical interfaces and can connect sensors to control devices. The student is also able to integrate a sensor into a fieldbus system.

Content

Fundamentals of sensor and measurement technology,
protection classes,
binary (on/off) sensors,
presence-detection sensors,
sensors for measuring physical quantities,
motion measurement, and
the basics of machine vision.
Factors affecting sensor selection, such as durability in the intended environment.
Sensor wiring and measurement exercises in the laboratory.

Qualifications

Basics of automation, basics of digital technology or respective skills and knowledge.

Assessment criteria, satisfactory (1)

The student is able to describe the basic operation and key concepts of sensors. They are capable of diagnosing faults in basic sensors and replacing a defective sensor with an appropriate equivalent.

Assessment criteria, good (3)

The student describes the fundamental concepts related to sensors, their operating principles, and their key electrical and mechanical characteristics. They are able to apply their knowledge to solving different types of problems and to select an appropriate sensor either to replace a defective one or for a new application.

Assessment criteria, excellent (5)

The student provides an in-depth description of the concepts, operating principles, and characteristics of various sensors. They are able to independently select not only basic sensors but also special-purpose sensors for different applications and environments in a manner that supports sustainable development – for example, by considering service life, maintainability, and energy efficiency.

Materials

Lecture materials, lecture examples, laboratory assignments, and product and programming manuals provided by equipment suppliers.
