Define/ what is E& I engineering - Instrumentation engineering is one of the complicated but sophisticated branches of engineering discipline which may be studied as a separate branch or along with electronics engineering. Both the courses more or less similar.

Details of E&I, I&C engineering

  • Instrumentation engineering is a branch of electrical and electronic engineering that is concerned with the study of engineering principles and procedures of computing instruments used in designing and assembling automated systems.
  • The work of instrumentation engineers is critical in the industrial manufacturing sector as they are required to construct, design, and maintain instruments and systems of an industry and decide on the type of instruments needed for better quality and efficiency of the products.
  • Some examples of Instrumentation - Modern automobiles have complex instrumentation. In addition to displays of engine rotational speed and vehicle linear speed, there are also displays of battery voltage and current, fluid levels, fluid temperatures, distance traveled and feedbacks of various controls (turn signals, parking brake, headlights, transmission position).
  • Cautions may be displayed for special problems (fuel low, check engine, tire pressure low, door ajar, seat belt unfastened). Problems are recorded so they can be reported to diagnostic equipment. Navigation systems can provide voice commands to reach a destination.
  • Automotive instrumentation must be cheap and reliable over long periods in harsh environments. There may be independent airbag systems which contain sensors, logic and actuators.
  • Anti-skid braking systems use sensors to control the brakes, while cruise control affects throttle position. A wide variety of services can be provided via communication links as the On Star system. Autonomous cars (with exotic instrumentation) have been demonstrated.
  • Air traffic control radar is distributed instrumentation system. The ground portion transmits an electromagnetic pulse and receives an echo (at least).
  • Aircraft carry transponders that transmit codes on reception of the pulse. The system displays aircraft map location, an identifier and optionally altitude. The map location is based on sensed antenna direction and sensed time delay. The other information is embedded in the transponder transmission.

On the Job

A control and instrumentation engineer is essentially responsible for designing, developing, installing, managing and/or maintaining equipment which is used to monitor and control engineering systems, machinery and processes. Tasks and responsibilities, which are common to instrumentation engineers, may include:

  • Designing and developing new control systems
  • Maintaining and modifying existing systems
  • Working collaboratively with design engineers, operation engineers, purchasers and other internal staff
  • Project management within cost and time constrained environments
  • Troubleshooting and problem-solving
  • Understanding and ensuring compliance with the health and safety regulations and quality standards
  • Providing advice and consultancy support
  • Domain expert in IT industries
