Apprentices will learn to describe and explain the make-up of an automatic control loop, the function of each of the control loop elements and the terms used to describe the loop performance and characteristics, perform mathematical functions associated with offset math and apply the concepts to common signaling systems use used in process control systems. Course will examine the principles, methods and devices used to measure flows, temperatures, pressures, levels, and densities in various industrial process applications. Course will explore common methods and types of equipment used to measure chemical components of a material or stream. This course was formerly the MOD-11 unit in related instruction.
