Instrumentation is a branch of Engineering which deals with measurement of various physical quantities like temperature, pressure, level, flow, speed, sound, light intensity and control of the same in various industries.
WHAT IS INSTRUMENTATION ENGINEERING?
Instrumentation system is widely used in industries viz. automobile, pharmaceuticals, chemical, fertilizers, power plants, pollution control, biomedical, food processing, electronic product manufacturing, and textile. With the advancement and widespread applications of electronics and computer in instrumentation and control the syllabus is framed to include core courses of electronics as well as computer engineering.
After passing the Degree Course in Instrumentation Engineering, the students find a wide range of jobs in all sectors of industries ranging from automobile to fertilizer. The pass outs are absorbed in power plants, Fertilizers & Chemical industries, Petro-chemical industries, Pharmaceutical Industries, Cement Factories, Health Care Services, Consulting Services, Navigational & Aerospace Organization, Food Processing Industry, Weather Stations to name a few.
Further students also get abundant opportunities for higher studies in Indian & Foreign universities. The professional practices include: Marketing, Sales & Service, Production, Turn Key Project, Consultation, Supervision, Design, Entrepreneurship & other related activities.Students also can pursue research in cutting edge technology, currently understudy.An Instrumentation Engineer is invariably required where there is a engineering activity.

DUTIES OF Instrumentation Engineer IN POWER PLANT
- Turbine control system testing, tweaking and commissioning
- Plant DCS system (Boiler and BOP) testing, tweaking and commissioning
- Plant SCADA system (electrical switchgear control) testing and commissioning
All the above work involves more or less the same type of work
- Testing (occasional calibration and replacement) of Plant field instrumentation
- Testing and commissioning of plant control valves (loop checking and ensuring proper feedback)
- Testing commissioning of plant solenoid valves (proper operation and feedback
- Testing and commissioning of plant MOV (with electrical engineer, this by far in my opinion is the most back breaking work and in the quest of complete automation there are literally 50-100 MOV’s in each co generation plant, i don’t know MOV’s and me do not go well )
- Testing and commissioning of plant servo’s (a very subtle art )
- Testing and calibration of plant measurement circuits, pressure, temperature, flow, speed, position and vibration probes. They also take a lot of time mainly because they form a major quantity of the plant instrumentation.
- Testing and commissioning of plant analyzers, In boilers, it will be PH, silica, conductivity, phosphate, SOx, NOx, CO, unburnt fuel and oxygen analysers. This work as far as i have seen is exclusively done by the vendors. all you have to do is to verify the operation and sign :).
- Testing and tweaking of graphics, minor modifications in consultation with plant operating personnel.
- testing and tweaking of control constants and minor (to sometimes major) logic modifications in application code to the controllers.
- hanging around a lot of time in marshaling units, RTU’s, in the field and in front of the controller, thinking, scratching your head and desperately wising to god that atleast this should work.
- Testing and commissioning of other plant systems, which do not form the part of the typical turbine and DCS control. They include
- Turbine and generator CO2 release system
- Plant and Trubine heat sensors and fire detectors panel
- MCP (manual call points) system and associated auxiliaries
- Plant communication system (another exclusive vendor area)
