Instrumentation heavily falls upon the category of Applied Physics in modern engineering subjects & both share the large part of engineering as far as their individual domain is concerned. Instrumentation mainly deals with electronics based instruments & process controlling systems in large engineering enterprises such as oil, gas, power, shipping corporation et al. On the other hand Electronics engineering are mainly concerned with power emitters. Generating electricity to transmit energy & using transmittance energy as electricity to process information signifies the mechanical & autonomous ethos of heavy engineering enterprises. . Instrumentation & Electronics engineering has been traditionally broken into several sub-disciplines including instrumentation engineering or rather both mechanical & electrical engineering, turbine engineering, boiler operation engineering, electronics circuit design et al. Since energy is considered as power so its production, control & distribution largely falls upon the division of Electrical Engineering. Thus, Instrumentation & Electronics are not separate but both provide a mechanical definition of any large scale industrial production process.
Most colleges under technical guidance standard approval provide specialization in Instrumentation & Electronics engineering subjects in degree level engineering courses. B.E. or B.Tech in Electrical engineering or Electronics is the entry point to understand Power dynamics & electronics in Master’s degree level. Government has been employing recent passed out students from in various researched based assignments upon electronics engineering projects. JEE or AIEEE may reach you towards prestigious engineering colleges to avail certificate in B.Tech. Moreover, to start your career in either electrical, mechanical or electronics engineering you should qualify GATE.
