Maintenance of Instruments & Systems

Learn maintenance and troubleshooting from the experts who have maintained both pneumatic and single-loop electrical/electronic devices as well as higher-level, microprocessor-based control systems. Covering the fundamental principles, vocabulary, symbolism, standards, and safety, this book provides the basic knowledge required of I & C technicians. The essential requirements for a maintenance department are well-documented, which include documentation control, office and shop layout, and department organization. Practical applications, including power, grounding, isolation, calibration, and basic troubleshooting techniques, are also covered. This book highlights the benefits of the systems approach, which looks at the whole picture to gain an understanding of the process rather than looking at each component separately. Examples and case studies of configuration, programming, calibration, and tuning of larger DCS systems, as well as single-loop devices and pneumatic devices, are shown, with an emphasis on applications rather than theory. Instrument symbols and uses, specifications, drawings, diagrams and schematics, and control algorithms are explained.
