This book covers both the physical properties of sensors for converting physical quantities into digital data and the design of complex measurement and data analyzing systems. In respect thereof, a unique treatment of measurement and sensor systems is given from a physical point of view, wherein a focus is on innovative links between physics and engineering sciences. The acquisition of data by measurement systems equipped with appropriate sensors is a fundamental activity in science and industry. In a connected world, the field of measurement and sensor systems can be regarded as an enabling technology for other fields of research and development, e.g., for electronics, chemistry, biology, and environmental monitoring. The book is divided into eleven chapters, each chapter starting with a discussion of measurement systems based on the relevant sensor concept followed by an in-depth description of the data processing and analysis procedures. After an introduction presenting fundamentals of measurement systems, digital measurement systems are addressed in detail. Then, operational amplifiers and measurement bridges as well as measurement signal processing methods are presented. After discussing transducers based on ohmic, capacitive, and inductive effects, temperature measurement systems are described. A separate chapter is devoted to optical measurement and sensor systems which represent a field of increasing importance.
