Industrial Process Control & Instrumentation / Level Two Advanced Process Measurement & Control

Overview

Course Description

This 32-hour training program uses a hands-on approach providing students an in-depth understanding of industrial process measurement & control systems. Participants will learn to apply more comprehensive measurement and control principles, terminology, symbols and documentation standards. In addition, students will perform hands-on exercises in which they will build, test, tune and troubleshoot temperature, pressure, flow & level control systems.
