A modern plant can have high-specification instruments, a capable control system, and a data historian holding thousands of tags-and still operate far below what its equipment can actually deliver. The problem is rarely one failed device. More often, performance is lost across the chain: sensor location, installation effects, calibration, signal conditioning, controller tuning, final-control-element mechanics, data quality, and operating decisions. The result is extra operating margin, slower transitions, and longer product holds than the process requires.
Process Instrumentation & Control treats the production system as one continuous engineering chain, from process physics to measurement, information, decision, action, and verification. Across twenty-two chapters and more than five hundred illustrated pages, it shows how information is created, transformed, and sometimes degraded at every interface-and how to diagnose the system as a whole instead of treating each discipline in isolation.
Inside this handbook, you will learn how to:
- Trace a weak control loop to its real cause by separating sensor, installation, signal-conditioning, tuning, and final-element problems.
- Judge whether a measurement deserves trust using accuracy, precision, uncertainty, calibration, and traceability as practical engineering tools.
- Work confidently with pressure and differential pressure, flow, level and interface, temperature, and analytical measurement.
- Specify and diagnose valves, actuators, variable-speed drives, instrument wiring, power, grounding, and hazardous-area interfaces.
- Perform calibration, commissioning, and loop checking as evidence-producing disciplines while maintaining recoverable plant documentation.
- Tune PID loops with process dynamics in mind and apply cascade, feedforward, ratio, multivariable, constraint, inferential, and model-predictive control where appropriate.
- Integrate functional safety, alarm management, and industrial cybersecurity across the plant lifecycle.
- Apply soft sensors, digital twins, machine learning, predictive maintenance, and edge computing only when the underlying measurements and data context can support them.
Key topics include measurement science and uncertainty; sensors, transducers, and installation effects; pressure, flow, level, temperature, and analytical measurement; valves, actuators, and drives; signals, wiring, grounding, and hazardous-area practices; P&IDs, tags, loop diagrams, datasheets, and instrument indexes; calibration, commissioning, and asset management; process dynamics and advanced control; PLC, DCS, and supervisory architectures; industrial communications and interoperability; functional safety; alarm management; cybersecurity; digital twins; soft sensors; analytics; machine learning; predictive maintenance; brownfield modernisation; troubleshooting; and staged smart-plant implementation.
Each chapter begins with a realistic operating problem-a startup that will not settle, a night-shift alarm on a recovery vessel, or a compressor trip that floods the operator with consequential alarms-then reconstructs the engineering that explains it.
Written for instrumentation and control engineers, process, chemical, and mechanical engineers, maintenance and reliability technicians, automation and control-system specialists, operations and production staff, plant data teams, and engineering managers, this handbook provides a complete view of the modern plant, one interface at a time.
