Essentials of Modern Measurements and Final Elements in the Process Industry: A Guide to Design, Configuration, Installation, and Maintenance Gregory K. McMillan
" by , published by the International Society of Automation (ISA) . It serves as a comprehensive resource for understanding smart technologies in sensors, transmitters, and control valves. Core Guide Overview
: Covers how smart features and digital positioners have increased installed accuracy by an order of magnitude while dramatically reducing transmitter drift. Essentials of Modern Measurements and Final Elements in
uses embedded sensors, edge analytics, and machine learning models to detect subtle failure patterns that humans or traditional algorithms might miss. This transition from preventive to predictive is one of the most transformative steps in the evolution of Industry 4.0.
While sensors gather data, final control elements execute the physical adjustments commanded by the distributed control system (DCS) or programmable logic controller (PLC). Control Valves Core Guide Overview : Covers how smart features
That era is ending.
Smart transmitters continuously track internal variables to identify maintenance needs before a failure occurs. While sensors gather data, final control elements execute
In critical processes, design a manual bypass loop around the control valve so the process can continue running during valve maintenance.
Modern transmitters feature build-up detection, loop integrity checks, and sensor drift alerts.
Field measurements provide the only window into what is really happening in a process. Any technical job in the process industry—whether in research, process development, design, automation, operations, or maintenance—depends upon the ability to see, trend, analyze, diagnose, and collect information from measurements. You cannot control or protect something you cannot measure, and the performance and integrity of both control systems and safety systems depend upon the accuracy, reliability, and speed of these measurements.
