In the minds of Instrumentation Engineer:-
As an instrumentation engineer, there are few things that we need to know to work in our workplace. the major thing being the process of the plant in which we work. it can be a small shop floor to a huge oil field.
We may be part of a product development group which develops automation products for industries or we may be part of the design and development team which does the detailed engineering or we may be part of maintenance for plants like cement plant, sugar plant, power plant, oil and gas, refineries, etc.
Our job lies somewhere in every aspect of a process as long as it needs process control to control, maintain and sustain process through instruments, we need to understand the process which gives a better edge in the work we do.
Instrumentation has its reach from the simple valve on/off control to complex logic implementation for closed-loop analysis which puts the instrumentation team in control of the whole process. There is also the usage of PLC/DCS in automation industries to ease the plant operations which again is part of the instrumentation team’s job as only an instrument engineer knows about the process in and out.
So an instrumentation engineer should know:
- Process In and Out
- Calibration and Measurement
- DCS or PLC Control Systems
- PID control loop analysis and tuning
In addition to the above list, Instrumentation engineers mostly deal with maintenance (i.e. preventive maintenance and corrective maintenance) of field instruments.
Instrument engineers also look after integrated control systems like Basic Process Control System (also known as DCS), Emergency Shutdown Systems (also known as SIS), Fire & Gas Systems(FGS).
Analyzers, Control valves, pressure-relieving devices, etc are also maintained by instrumentation engineers.
we can study one by one on each topic. Read this Instrumentation Guide.
GOD is the PID controller and human beings are the process loads.
