Instrumentation and control Engineering is a vast field. It primarily deals with automation, field instruments and final control elements that measure and control various physical parameters such as temperature, pressure, flow etc. Its application is very vast including bio-med, chemical, oil & gas, power and many more. The off-beat application of building and airport automation is coming up and instrumentation has a huge role in it. Robotics is another interesting field that requires multidisciplinary skills including Instrumentation and Control.
An instrument engineer learns the basics in terms of how the instruments work as well as how to sense the physical parameters and convert them into digital data and use it to control the various processes in an instrument e.g. the climate control system.
