Process control is employed in continuous production – in manufacturing and other professions and industries where a continuous stream of material is generated – as well as in "batch processing." It is used to autonomously regulate the manufacturing conditions of a product, assuring superior quality and efficiency. Process control, in its simplest form, combines control engineering and chemical engineering – and relies on specialised, often custom-built industrial control systems. These systems regulate the flow, output, mixing, and other parameters of a continuous manufacturing process in response to input from sensors, data monitoring systems, and other sources. Process control systems function at a significantly higher degree of sophistication and power than a system that is entirely managed by people. The system is fully automated and operates on analogue data supplied from metres and sensors to specialist computers that allow for continuous flow, pressure, and temperature control. This book is a compilation of chapters that discuss the most vital concepts in the field of process control. It provides in depth knowledge of this field of study. It deals with control characteristics, tuning and control systems with multiple loops. It also explores final control elements, process control systems, signal conditioning and digital controllers. Some of the diverse topics covered in this book address the varied branches that fall under this category. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. The book studies, analyses and upholds the pillars of algebra and its utmost and significance in modern times. This book is an essential guide for students who are seeking detailed information in this area.
