Instrumentation and Control Engineering

Instrumentation and control engineering Instrumentation  is defined as the art and science of measurement and control of process variables within a production or manufacturing area. [1]  The process variables used in industries are Level, Pressure, Temperature, Humidity, Flow, pH, Force, Speed etc.  Control engineering  or control systems engineering is the engineering discipline that applies control theory to design systems with desired behaviors.Control engineers are responsible for the research, design, development and control devices/systems, typically in manufacturing facilities and plants The practice uses sensors to measure the output performance of the device being controlled and those measurements can be used to give feedback to the input actuators that can make corrections toward desired performance. When a device is designed to perform without the need of human inputs for correction it is called automatic control (such as cruise control for regul...
