Introduction

The field of Applied Electronics and Instrumentation Engineering is growing at a very fast pace. Over the past three decades the field of instrumentation has seen an extremely widespread application in almost all discipline of engineering e.g., Mining & Metallurgy, Robotics, Textile, Rolling Mills, Cranes & Hoists, Arc Furnaces, Chemical Engineering, Process Control, and Static Relays etc. Today, the application of Microprocessor / Microcontroller and Digital Signal Processor (DSP) Chip has revolutionized the field of Electrical and Electronic Instrumentation. These Microcontroller / DSP chips have virtually become the heart of modern instrumentation design. Although, the new technology has resulted in more versatile, compact, accurate and faster response time, as compared to the conventional design, the new systems are replacing the old rather slowly due to reliable performance of the old systems.

What do instrumentation engineers do?
Instrumentation engineers are prepared to work in the pulp and paper industry, engineering firms, petrochemical plants, mining industry, sales and service companies, oil refineries, gas plants or consulting firms as: instrumentation technologists, engineering technologists; control technicians, technical representatives with a job profile of Detailed engineering of field instrumentation, control systems, ESD and F&G systems.

Why Applied Electronics & Instrumentation?
Electronics is a basic discipline providing materials, devices and systems for a number of fields including computers and information, communication and transportation, manufacturing and construction, medical and biological engineering, as well as health and welfare engineering, and will continue to increase its importance as the source of advanced technologies in the 21st century.
Nowadays Instrumentation & other fields are becoming increasingly interdisciplinary in nature where Instrumentation provides the monitoring and controlling hands for the process Automation. Instrumentation is nothing but the eyes and ears of the process through which Instrumentation Engineers know the condition of plants. With Instrumentation scheme control system design implies identification of control objectives; selection of appropriate measurements and manipulations, as well as determination of loops connecting these and identification of proper control laws. Also the advent and rapid growth of digital computers has revolutionized the practice of process control and allowed the industrial implementation of the advanced control concepts.
