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.
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.
[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]
Control system design varies from trivial to a separate specialty. Instrumentation engineers are responsible for integrating the sensors with the recorders, transmitters, displays or control systems, and producing the Piping and instrumentation diagram for the process. They may design or specify installation, wiring and signal conditioning.
Applied Electronics & Instrumentation Engineering is an advanced branch of engineering which deals with the application of existing or known scientific knowledge in electronics, instrumentation, measurements and control for any process, practical calibration of instruments, automation of processes etc.
The huge growth in process control instrumentation was boosted by the use of pneumatic controllers, which were used widely after 1930 when Clesson E Mason of the Foxboro Company invented a wide-band pneumatic controller by combining the nozzle and flapper high-gain pneumatic amplifier with negative feedback in a completely mechanical device ...
The term process automation is essentially synonymous with process control. Process controls (basic as well as advanced) are implemented within the process control system, which may mean a distributed control system (DCS), programmable logic controller (PLC), and/or a supervisory control computer. DCSs and PLCs are typically industrially ...
