Applying heat exchanger control strategies

Inside Process: Integrating control schemes, such as feedback, cascade, and feedforward techniques, can satisfy the control requirements of even highly challenging heat exchanger temperature control applications.

Six steps to choose between PLC and DCS for process industries

Cover story on controllers: Learn how to choose between PLC and DCS.
