【 摘 要 】

In the design of measurement systems we face the fact that parameters are subject to (measurement-) uncertainties. Additionally, components may behave entirely different from what is specified, which is then considered a fault. Consequently, both uncertainty as well as probability of failure should be considered in education on robust design and reliability. In this paper we present a teaching concept based on hardware fault injection using a simple level sensor system as an example. Learning objectives are faults, errors, failures, false alarms versus misses as well as advantages and disadvantages of redundancy.
