Instrumentation Engineering is a specialised branch of Electrical and Electronics Engineering, primarily focussing on the principles and operations of measuring instruments used in the design and configuration of automated systems. Instrumentation technology helps create, construct and maintain measuring and control devices and systems found in manufacturing plants and research institutions. Hence those with B.Tech. and M.Tech. degrees in Electronics, Applied Electronics and Instrumentation Engineering can find jobs in these fields. Public-sector companies such as Instrumentation Ltd., Bharat Electronics Ltd. and Bharat Heavy Electricals Ltd. provide job opportunities. Instrumentation Engineering is the basis of mechatronics and robotics engineering. Its main objective is to ensure that systems and processes operate safely and efficiently. Several institutions offer higher study facilities in Instrumentation and Instrumentation and Control Engineering or related branches such as Applied Electronics and Instrumentation Engineering.
