Electronics and Instrumentation

Nature of work of an instrumentation engineer ranges from designing, developing, installing, managing equipments that are used to monitor and control machinery, finds Sumit Bhattacharjee Just imagine a world without instruments. It would be like traversing into a time that probably goes even beyond the Stone Age. Man has always been fascinated towards instruments and the quest to invent and innovate on new instruments has pushed mankind beyond barriers to an age where instruments have become a part and parcel of the life. Today, we find instruments at home and at workplace, and this was possible only because of the science instrumentation.

In scientific terms, instrumentation is defined as the art and science of measurement and control of process variables within a production, or manufacturing area. The science has further opened up the realm of instrumentation engineering.

Electronic and instrumentation engineering is associated with development as well as implementation of electronic and electric instruments for recording, measuring and monitoring physical phenomena. Subjects studied under this course are designing of analog and digital electronic devices and micro-controllers programming etc. it holds great future in the field of making super integrated chips which can speed the computer process and it's efficiency will go up exponentially enabling faster transaction on the net ,it has it'great implications on checking the standards of electronics instruments for future.Electronics and instrumentation is a field which relates to manufacturing of chips, cell phones,Medical appliances like ECG,TMT,ESR testing machines,It also had found applications in aeronautical fields. Instrumentation plays a vital role in manufacturing industries.

The discipline of instrumentation engineering branched out of the streams of electrical and electronic engineering some time in the early part of 1970s. “It is a multi-disciplinary stream and covers subjects from various branches such as chemical, mechanical, electrical, electronics and computers,” says Prof. A. Bhujanga Rao, from the department of Instrumentation Engineering, Andhra University.

The growth in the avionics, aeronautical and space science sectors has also increased the scope for instrumentation engineers. Instrumentation engineers can also fit in both software and hardware sectors.

Apart from covering core subjects such as system dynamics, industrial instrumentation and process control, analytical and bio-medical instrumentation and robotics, the students deal with software and hardware topics such as microprocessor and micro controller based instrumentation, VLSI and embedded system designs, computer architecture and organisation and computer control of processes. Computer languages such as ‘C' and Fortran are also part of the curriculum. This makes an instrumentation engineer fit for both the hardware and the software industry. Moreover, since instrumentation engineers are presumed to be good in physics, the logical ability is expected to be on the higher side, which is a basic quality needed to excel in the software industry.

The demand is so high that every student finds at least two jobs waiting in the wings, by the time he or she completes her course, says Dr. Bhujanga Rao.

“Though there is a demand for instrumentation engineers from the software sector, we prefer the core area, as that is where we can showcase our creativity and knowledge,” says Srinivas a third-year student.

The shift towards core sector is not only due to the opportunity to showcase ones creative talent and knowledge, but also because of the long term stability and quick growth. Bio-medical is another area that is fast catching up and there is huge requirement for instrumentation professionals.

Instrumentation engineering that made its way as an exclusive engineering discipline in the early part of 1970s was earlier known as M.Sc. Tech Instrumentation in many of the colleges. It was then a three-year PG course. Even today, it is referred to by different names by various colleges. While some call it as B. Tech- electronics and instrumentation, a few name it as B. Tech – control and instrumentation. Whatever, be the name, the curriculum is the same.
