Sensors for safety and process control in hydrogen technologies

Abstract

This book is about devices commonly called sensors. These devices are designed to measure physical or chemical quantities and to deliver an electrical output signal in relation to theses quantities. Sensors offer new possibilities for safety as well as process monitoring and control. They are to some extent in competition with traditional analytical instrumentation in terms of acceptance and perceived performance. Sensors have the potential to augment or even supplant traditional analytical instrumentation. These devices offer numerous advantages over so-called traditional analytical instrumentation because they are generally small sized, economical, and readily manufacturable. Sensors are compatible and integrable into electronic systems for on-site, real-time safety monitoring and process control. These features are of great importance for applications in current and emerging technologies, including hydrogen technologies, which is the topic of this book.
