Instrumentation Engineering

Instrumentation technology refers to devices that measure or control pressure, flow, currents and speed for gas, electrical, chemical and other systems. Input instrumentation is used for measuring, regulating physical quantities such as flow, level, pressure, temperature and so on. Output instrumentation includes control devices such as valves, regulators, circuit breakers and relays.

Instrumentation engineering is the engineering specialization focused on the principle and operation of measuring instruments that are used in design and configuration of automated systems in electrical, pneumatic domains etc and the control of quantities being measured.

They typically work for industries with automated processes, such as chemical or manufacturing plants, with the goal of improving system productivity, reliability, safety, optimization and stability. To control the parameters in a process or in a particular system, devices such as microprocessors, microcontrollers or PLCs are used, but their ultimate aim is to control the parameters of a system.
