There are limited places available to ensure a superior learning experience for our students.
This practical course covers all the essentials of process control and tools to optimize the operation of your plant and process, and regards the process, from the primary measuring device, through the controller, right down to the final control element as a chain with important links. Controllers need to be carefully matched to the process to work optimally; this matching procedure is called tuning. Controllers that are not correctly configured and tuned will not perform optimally and will not reduce variability in the process as they should. It is aimed at engineers and technicians who wish to have a clear, practical understanding of the essentials of instrumentation and final control elements typically found in common loops. It incorporates loop tuning, as well as how to optimize the operation of their particular plant or process. Mathematical theory has been kept to a minimum with the emphasis throughout on practical applications and useful information.
But it does not stop there. Advanced Process Control (APC) is an essential part of the modern plant. Small differences in process parameters can have large effects on profitability; get it right and profits continue to grow; get it wrong and there are major losses. Many applications of APC have pay back times well below one year. APC does require a detailed knowledge of the plant to design a working system and continual follow up along the life of the plant to ensure it is working optimally. Cascade Control, Feedforward control, control with long dead times, IMC and MPC are all considered, with respect to different applications. At the end of this course you will have the skills to troubleshoot / tune / deal with / understand a wide variety of process loops.

In order to meet the exacting demands of the oil and gas, mining, manufacturing and downstream processing industries, modern plants are equipped with systems and devices which are needed to measure and regulate variables such as temperature, pressure, flow, humidity, liquid level, velocity and density. Industrial Automation provides the technology to control and monitor a process plant using such concepts as feedback, cascade, feedforward and advanced process control. Here at the Engineering Institute of Technology (EIT), we have developed industry-focused programs in the form of vocational diplomas, advanced diplomas and graduate certificates, all the way up to Masters level in the higher education sector.
There is a critical shortage of automation, instrumentation and control engineers, technicians and technologists around the world now due to the retirement, restructuring and rapid growth in new technologies and industries. The respected International Society of Automation (ISA) organization estimated that at least 15,000 new automation engineers are needed annually in the USA alone.
In keeping with the philosophy of EIT, students in this school are exposed to the practical, up-to-the-minute knowledge and skills demanded by leading industries worldwide, with online instrumentation courses. EIT does not just cater to a generic student body, instead all of our online instrumentation courses are specific to industry. The programs cover a large range of topics and are suited to anyone needing an intensive and practical look at all facets of industrial automation, instrumentation and process control.
The short courses that form part of EIT's professional development series are designed to provide students with critical knowledge and practical tools that can be immediately applied to the workplace. They are ideal to up-skill and/or cross-skill in a particular area or technology and are not accredited programs.
Students in EIT's School of Industrial Automation, Instrumentation and Process Control study subjects which include: process control, instrumentation, control valves, process plant layout and piping design, tuning of process loops, SCADA, PLCs, advanced process control (APC), boiler control, hazardous areas, safety instrumentation (IEC 61511 and IEC 61508), HAZOPs, industrial data communications, networking, deviceNet and Fieldbus, industrial wireless, radio telemetry systems, shielding/EMC/EMI, and noise reduction.
