ELM 5070 - Instrumental & Process Control

The Process Control Training Systems form a complete program designed to familiarize students with the fundamentals of instrumentation and process control. It demonstrates the control of pressure, flow, level, temperature and pH processes. The main objective of the course is to teach the operating principles, measurement and control of pressure, flow and level processes. In addition, students gain valuable experience tuning closed-loop processes using the most frequently encountered industrial methods.

Student Learning Outcomes:
