Sensor Performance and Reliability

Technological advances abound in today’s world of instrumentation but much of it depends on conventional sensing technology that has been around for more than 50 years. Many of the instrumentation or sensor problems that exist today are similar to those which we have seen over the past years. Addressing these problems, this book describes several new instrumentation testing, diagnostics, and analysis techniques to verify the reliability, health, and performance of process instrumentation. This book helps you understand how to objectively assess the accuracy, response time, residual life and other characteristics of installed instrumentation and offers a practical means to identify the problems, assess their consequences, and help resolve some of the problems. It provides applications in a number of industries such as power, chemical, aerospace, and others. In-situ methods for sensor response time testing and calibration, on-line measurements to identify blockages and voids in pressure sensing lines, and other examples are covered.

In-situ methods for sensor response time testing and calibration, on-line measurements to identify blockages and voids in pressure sensing lines, and other examples will be covered "Biodegradable Polymer Blends and Composites from Renewable Resources provides a comprehensive, current overview of biopolymeric blends and composites and their applications in various industries. The book is organized according to the type of blend or composite. For each topic, the relationship between the structure of the blends/composites and their respective properties is explored, with particular focus on interface, compatibility, mechanical, and thermal properties. Real-life applications and potential markets are discussed. This is a premier reference for graduate students and researchers in polymer science, chemical and bio engineering, and materials science."--Publisher
