Lab Class Announcement SS 2024:

Objectives and Content:

  • The Lab is coordinated with the lecture "Measurement and Control Systems". While the lecture is focusing on principles and sub-systems, the Lab focuses on measuring methods for the most important industrial measured variables.


  • Knowledge of the lecture "Introduction to Measurement and Control"
  • Annotation:

    Each experiment begins with a 30-minute colloquium. It is checked whether you are familiar with the substance and the content of the experiment. You may only carry out the actual experiment if you have passed the colloquium. Thorough preparation of the respective experiment is a prerequisite for passing the colloquium.


  • Registration on this website from April 3rd, 2024, 10:00 a.m. - April 24, 2024, midnight
  • The Lab must also be registered as an examination in the CAS of the KIT!

Experiment instructions:

  • Brief description of the experiments:
    • A1 Measurement of temperature:
      In this experiment, the theoretical basics of temperature measurement and the calibration of thermometers are introduced. The students get to know different forms of temperature measuring devices and can try to operate them. The focus of the experiment is contact-based thermometers, pyrometers and thermal imaging cameras will also be used and discussed.
    • A2 Measurement of lengths:
      The experiment "A2 Distance measurement" deals with the principles of different distance measurement methods and discusses their advantages and disadvantages. The linear behavior of a differential immersion anchor transducer will be used as an example of inductive displacement measurement. With the capacitive displacement transducers, the error behavior of a cylinder capacitor with a movable dielectric will be examined. The experiment setup of an absolutely coded encoder illustrates the functionality and error behavior of different codings. Laser triangulation with image evaluation will be used as the optical displacement sensor. Finally, a sonar-based runtime measuring method will be demonstrated.
    • B1 Bridge circuit & measurement principles:
      In everyday life, we often encounter simple measuring tasks, such as determining the mass of an object, however, it cannot be recorded without aids. It often makes sense to convert the physical quantity into another quantity. Since the data are usually be processed electronically, the task is to convert the variable of interest into the change of voltage or resistance. In this experiment, various principles for measuring physical quantities are presented. The measuring methods and interference compensation are illustrated using the example of the bridge circuit with strain gauges.
    • B2 A/D - Signal processing:
      This experiment deals with the digital processing of analog signals. For this purpose, the necessary mathematical and metrological basics are repeated independently. During the experiment, the theory is practically reproduced using the digital processing of audio signals.
    • C1 Measurement of stochastic signals:
      This experiment is divided into 2 parts. In the first part, the acceleration of gravity is estimated from a series of observations. The gravitational acceleration is derived from the measured height of fall and the duration of the fall of a ball. In addition to the actual determination of the measured value (acceleration of gravity), a discussion of the measurement accuracy is essential, since without accuracy the measurement result has no meaningfulness. In part two, the Kalman filter is presented and explained using a clear example.
    • D1 System identification on the electric motor:
      During the experiment, the frequency response curves of two systems are to be determined. The robustness of the method in the presence of interference will be demonstrated using an RC element. Then, using an asynchronous motor as an example, a linearized control element around an operating point will be examined.
    • D2 Inverse pendulum:
      The overhead pendulum is a pendulum attached to a motorized slider. By swinging up, the pendulum is moved over the slider and should be balanced there. To do this, the pendulum position is used as an input for a controller that balances the pendulum. The task is to model the pendulum and adjust the controller.
    • D3 Mobile Robot platform:
      In this practical experiment, the functionality of a quadrocopter will be illustrated. The aim is to autonomously follow a red line on the ground, which is represented by a flexible rope. As a necessary preparatory work, the system's PID controllers for height and yaw angle must be set using the Ziegler-Nichols method. The detection of the line on images from the camera pointing downwards must also be programmed.
  • Detailed test instructions are available on this website from mid-April each year
