Instrumentation term is commonly used in engineering, which means measurement and control for industrial process systems. Various processes in petrochemical, Oil & Gas, Power industries need to be maintained at controlled levels to get the desired product. It is commonly done by controlling such process variables as pressure, temperature, and liquid level; using measurement devices (instrument) with typical control systems.
Instrumentation plays a significant role in both gathering information from the field and changing the field parameters An Instrumentation engineer is responsible for designing, developing, installing, managing and/or maintaining equipment which is used to monitor and control engineering systems, machinery and processes. Instrumentation engineer ensure that these systems and processes operate effectively, efficiently and safely.
