This newly revised best-seller is ideal for instrumentation and control system engineers in the process industries who are responsible for designing, installing, and maintaining safety instrumented systems. Engineers, managers, technicians, and sales professionals employed by end users, engineering firms, systems integrators, and consultants can all benefit from the material presented here. Safety Instrumented Systems: Design, Analysis, and Justification, 2nd Edition addresses the increased realization that today's engineering systems-and the computers used to control them-are capable of large-scale destruction. When even a single accident could be disastrous, the luxury of learning from experience no longer exists. This book is a practical how-to text on the analysis, design, application and installation of safety instrumented systems.
