This volume is the most practice-oriented one in the book series 'Materials and Components of Electrical Engineering' to date. Based on the fundamentals described in the volume 'Sensors', industry experts detail the sensors in their specialized fields, with a focus on practical application examples. Equally important is the associated circuit technology: only with optimal design of the circuit peripherals can the sensor properties be fully utilized. The multitude of contributions provides an impression of the enormous range of modern sensor technology, applicable to both functional principles and application possibilities. In this regard, practitioners seeking the optimal solution for their tasks often face significant challenges. Therefore, the information in this book is likely to be an important support in many cases. This volume consciously emphasizes that no theoretical specialized knowledge is required, meaning the book is generally aimed at interested engineers and technicians, regardless of their prior education. The volume is thus equally important for the workshop as it is for the laboratory: the focus is on the practically applicable technical realization of the sensor system. The sentence structure of this book follows the proven model of the other volumes in this series. Once again, the experienced and dedicated work of G. Krummel from ArtType Kommunikation has resulted in a visually appealing book. Special thanks are also extended to Dr. I. Schlembach from B. G. Teubner Publishing for their continuous support, even in challenging times.
