Electrical and Instrumentation Engineering deals with the design of devices to measure physical quantities such as pressure, flow and temperature. It basically focuses on the study and application of electricity, electronics, and electromagnetism. Instrumentation engineering is a specialization on the principle and operation of measuring instruments used in design and configuration of automated systems in electrical, pneumatic domains etc. Industries with automated processes, such as chemical or manufacturing plants require Electricity and Instrumentation Engineering graduates for improving system productivity, reliability, safety, optimization, and stability. The design of such instrumentation requires a good understanding of physics that often extends beyond electromagnetic theory. Instrumentation is often dealt as the sensors of larger electrical systems.
