‘INSTRUMENTATION’ and ‘CONTROL ENGINEERING’, both the words are technical terminology. So further moving on let us see the meaning of both the terms separately.INSTRUMENTATION is termed the art and science of measurement and control of the process variables within the production of the manufacturing area. The variables used in industries are Level, Pressure, Temperature, Humidity, Flow, Force, speed, etc.

CONTROL ENGINEERING or in simple terms referred to as CONTROL SYSTEMS ENGINEERING is the engineering branch that applies control theory to design systems with desired characters and behavior. Control engineers are responsible for the research, designs, development, and control of devices or systems, typically in manufacturing industries and factories. Sensors are widely used mainly to measure the output performance of the device being controlled and that measurement is further used to give the required feedback to the input controller or in technical terms ‘actuators’. The actuator has the special characteristics that it can make the corrections toward the desired performance. When a device or a system is designed to perform without the influence of human effort and inputs for the correction then it is called AUTOMATIC CONTROL, for example, the speed controller used in lifts when it fails or breaks down. So further moving on let us see the basic requirement of an instrumentation and control engineer:-

Design and develop control systems

Maintaining the existing control systems

Managing the control systems

Troubleshoot

Ensuring the instruments and devices work properly with full safety measures

Ensuring the quality standards of the working devices

Basically, control engineering was all about the continuous system, but after the technological advancement, it interfered in the day-to-day human activities such as in designing various software such as CFD, AUTOCAD, and CAutoDetc had been introduced, which totally changed the era of computerized designing and technology.
