Multi-element pneumatic control system,s like all process control systems, operate primarily to maintain a process variable (such as level, temperature, flow, or pressure) at or near a predetermined value known as set point.
This interactive online course focuses on several types of multi-element pneumatic control systems that are commonly used in industrial plants. The basic design and function of the control system are explained, and emphasis is also placed on how the instruments and componenets in the system work together to keep a process variable at or close to set point.
