The history of instrumentation in industrial plants is intertwined with the evolution of automation and process control. Early industrial processes relied heavily on manual control, with operators manually adjusting valves, monitoring gauges, and making decisions based on their observations. As industries grew and processes became more complex, the need for more sophisticated instrumentation and control systems became apparent.

• Early Developments: The first industrial instruments were primarily mechanical devices, such as pressure gauges, thermometers, and flow meters. These instruments provided basic information about process conditions, but they required constant monitoring by operators.
• The Rise of Pneumatic Control: In the early 20th century, pneumatic control systems emerged as a major advancement. These systems used compressed air to transmit signals and actuate control valves, enabling more precise and automated control of processes.
• The Electronic Revolution: The development of electronics in the mid-20th century revolutionized instrumentation. Electronic sensors, transmitters, and controllers offered improved accuracy, reliability, and flexibility compared to their pneumatic counterparts.
• The Digital Age: The advent of digital computers and microprocessors in the late 20th century led to the development of sophisticated digital control systems, such as Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC). These systems enabled advanced control strategies, data logging, and remote monitoring.
• Modern Instrumentation: Today, instrumentation in industrial plants is characterized by advanced sensors, wireless communication, and sophisticated software. Technologies such as the Industrial Internet of Things (IIoT) and cloud computing are enabling new levels of automation, optimization, and predictive maintenance.

Key Milestones:

• Early 1900s: Development of pneumatic control systems.
• Mid-1900s: Introduction of electronic instrumentation.
• Late 1900s: Emergence of digital control systems (DCS and PLC).
• 21st Century: Adoption of IIoT and cloud computing in instrumentation.
