What Makes Analog Reality the Optimal Choice

Despite the advancements in digital control, analog solutions may still be the optimal choice for specific high-speed, continuous processes in industrial automation.

A recent article from partner publication Control highlighted the limitations of digital control systems in handling fast-acting processes.

The scenario presented in the article described how a seemingly advanced digital control system, involving a smart pressure transmitter and digital positioner, failed to adequately manage a burner management system (BMS) due to its inability to react swiftly enough to sudden changes in demand.

This underscores the importance of understanding the inherent benefits of analog systems, such as self-contained pressure regulators, which can provide immediate, continuous responses without the delays introduced by digital sampling.

The narrative also touches on the broader implications of the shift from analog to digital systems, emphasizing that while digital control systems offer vast computational advantages, they come with compromises. Historically, analog systems allowed for direct interaction with physical processes, ensuring a seamless connection between measurement and action.

Control delves further into the nuances of digitized reality in this article.
