Control and Instrumentation
Control and instrumentation engineers (C&I engineers) are responsible for designing, developing, procuring, installing, commissioning, managing and maintaining equipment which is used to monitor and control engineering systems, machinery and processes. So what does that mean for the C&I engineer involved in the oil and gas, petrochemical, process and pharmaceutical industries?
Well, the typical Control and Instrument Engineer will be expected to be fluent in electronics, fluid dynamics, material selection, control engineering, and systems engineering amongst all the usual competencies expected of today's professional engineer.
In any one day the C&I engineer could be expected to size an orifice plate, hook up a differential pressure transmitter across the plate, wire it via a hazardous area barrier into a control system (obviously complete with graphical interface and alarm points they have specified), configure the control loop, wire the controlled output to a control valve that they have sized and selected to be suitable for the fluid conditions, and of course ensure there is instrument air available to actuate the valve. And for good measure they will have to ensure the emergency shut down system has an appropriately high integrity level to drive the valve closed when required.
With all these demands it is no surprise then that Control and Instrumentation is often regarded as the "black art" of many an engineering house. However, we all know that to be good at their job the instruments man must be able to put their hands on the right information, quickly. This site aims to help you maintain the mystique.
Here is a small selection of the type of instrument and control information we provide:
