What is Electronics and Instrumentation Engineering?

Applied Electronics and Instrumentation Engineering is a high-level engineering discipline that deals with the application of existing or known scientific knowledge in electronics, instrumentation, measurements, and control for any process, practical calibration of instruments, process automation, and so on. It combines Electronics and Instrumentation Engineering. This is an industry-oriented engineering branch that requires more knowledge and experience in industrial applications to succeed. Many universities in India have implemented the course. Many universities offer various courses such as Electronics & Instrumentation Engineering, Instrumentation Engineering, and so on.

This branch is industry oriented and mainly looks at the production, management, and testing of already existing devices or the production of new devices. Apart from industrial instruments this field also explores other areas like bio-medical instruments and robotics.

Key Elements of Electronics and Instrumentation Engineering

There are certain subjects that are fundamental to electronics and instrumentation engineering, some of the key aspects of this course are :

Physics and Mathematics in Electronics and Instrumentation Engineering: In order to have a basic idea of how a device works one needs to know the physics behind it and how the calculations of the same device function. Hence a basic idea about calculus and physics is necessary and one needs to be interested in these subjects.

Basics of Electronics in Electronics and Instrumentation Engineering: In order to design and work on machines and other heavy devices, one should have a knowledge of how various circuits work and the theory behind electrical energy and its conversion. Electronics then functions as the foundation of this course.

Industrial Instrumentation in Electronics and Instrumentation Engineering: Industrial instrumentation involves controlling, and devising all physical quantities of industrial equipment, utilising and working with units like voltage, fluid pressure, temperature, and other such physical measurements and units.

Computer Programming in Electronics and Instrumentation Engineering: Computer programming is one of the key elements of this course because of the way it engages with both instruments and electronic devices. A basic understanding of computer programming and computer languages becomes necessary in order to explore the functions of various instruments and devices.
