UNDERSTANDING INSTRUMENTATION, CONTROLS & AUTOMATION SEMINARS

This 3 day seminar is intended for engineers, technologists and others who wish to learn how modern computer-based technologies are used to control HVAC, water & wastewater, manufacturing, petrochemical and other processes.

Using practical examples, the seminar introduces the fundamentals of process control and builds into more complex systems including PID control, SCADA and PLCs.

Intended for those who work in related disciplines such as electrical, mechanical, chemical and civil, the seminar utilizes a comfortable learning pace and live demonstrations. No electrical background is required.
