Instrumentation engineering is the science of the measurement and control of process variables within a production or manufacturing area. [1] Meanwhile, control engineering , also called control systems engineering, is the engineering discipline that applies control theory to design systems with desired behaviors.
A modern control room where plant information and controls are displayed on computer graphics screens. The operators are seated as they can view and control any part of the process from their screens, whilst retaining a plant overview. Process control of large industrial plants has evolved through many stages.
Instrument mechanics in engineering are tradesmen who specialize in installing, troubleshooting, and repairing instrumentation, automation and control systems.The term "Instrument Mechanic" came about because it was a combination of light mechanical and specialised instrumentation skills.
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...
Instrumentation is a collective term for measuring instruments, used for indicating, measuring, and recording physical quantities.It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology, automation, and control theory.
[6] This book is part of a series of inter-related manuals the AIAG controls and publishes, including: The measurement system analysis manual [7] The failure mode and effects analysis (FMEA) and Control Plan manual [8] The statistical process control (SPC) manual [9] The production part approval process (PPAP) manual [10]
Correct operation of the petrochemical process plant is achieved through the action of control loops. [1] These automatically maintain and control the pressure, temperature, liquid level and flowrate of fluid in vessels and piping. Control loops compare the measured value of a parameter on the plant, eg. pressure, with a pre-determined set point.
