Transistor electronics enabled wiring to replace pipes, initially with a range of 20 to mA at up to 90V for loop powered devices, reducing to 4 to 20mA at 12 to 24V in more modern systems.
The transistor was commercialized by the mids. Such devices could control a desired output variable, and provide either remote or automated control capabilities.
The transformation of instrumentation from mechanical pneumatic transmitters, controllers, and valves to electronic instruments reduced maintenance costs as electronic instruments were more dependable than mechanical instruments. This also increased efficiency and production due to their increase in accuracy. Pneumatics enjoyed some advantages, being favored in corrosive and explosive atmospheres. As technology evolved pneumatic controllers were invented and mounted in the field that monitored the process and controlled the valves.
This reduced the amount of time process operators were needed to monitor the process.
Later years the actual controllers were moved to a central room and signals were sent into the control room to monitor the process and outputs signals were sent to the final control element such as a valve to adjust the process as needed. These controllers and indicators were mounted on a wall called a control board.
The operators stood in front of this board walking back and forth monitoring the process indicators. This again reduced the number and amount of time process operators were needed to walk around the units.
The most standard pneumatic signal level used during these years was psig. Whilst the controls are centralised in one place, they are still discrete and not integrated into one system.
A DCS control room where plant information and controls are displayed on computer graphics screens. The operators are seated and 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. Initially, control would be from panels local to the process plant. However this required a large manpower resource to attend to these dispersed panels, and there was no overall view of the process.
The next logical development was the transmission of all plant measurements to a permanently-manned central control room. Effectively this was the centralisation of all the localised panels, with the advantages of lower manning levels and easier overview of the process.
Often the controllers were behind the control room panels, and all automatic and manual control outputs were transmitted back to plant.
However, whilst providing a central control focus, this arrangement was inflexible as each control loop had its own controller hardware, and continual operator movement within the control room was required to view different parts of the process.
These could be distributed around plant, and communicate with the graphic display in the control room or rooms.
The distributed control concept was born. The introduction of DCSs and SCADA allowed easy interconnection and re-configuration of plant controls such as cascaded loops and interlocks, and easy interfacing with other production computer systems.

First of all.. I would like to thanks to you from core of heart. This is really amazing collection for instrumentation engineer.
I will be learn each and every thing from here.. Once again thanks a lot sir.StartLearning, Inc.
The transformation of instrumentation from mechanical pneumatic transmitters, controllers, and valves to electronic instruments reduced maintenance costs as electronic instruments were more dependable than mechanical instruments. Sound and light application considerations Each topic is complete with diagrams, equations and other forms of graphical representations for better learning and quick understanding.
The chapter goes finally into inductance the least pure of all electrical quantities , time and frequency, mass, length and temperature. While traditionally a key area within mechanical and industrial engineering, understanding this greater and more complex use of sensing and monitoring controls and systems is essential for a wide variety of engineering areas--from manufacturing to chemical processing to aerospace operations to even the everyday automobile.
Power Control Quite sensibly, the author underlines that electrical and physical standards, far from being a close subject, are constantly under development and are changing with advances in quantum physics, laser technology and other pieces of scientific knowledge. A refrigerator maintains a constant temperature by measuring the internal temperature.
