Developing turbines and other advanced energy systems that can operate at extremely high temperatures boosts efficiency, thereby cutting operating costs and offering potential savings for consumers. Monitoring is critical to ensure that these complex systems run safely and effectively, with minimal downtime; however, the necessary ultra-high temperatures also introduce challenges in developing sensors that can withstand such harsh environments.
A recently completed NETL-managed project with Colorado-based Sporian Microsystems, Inc., produced smart temperature sensors that can operate up to 1800 degrees Celsius as well as pressure sensors that operate at temperatures up to 1600 degrees Celsius for improved performance in monitoring gas turbines, combustion systems and more. Extensive testing in relevant environments shows that the developed sensors offer the potential for greater durability, functionality and reliability at a more affordable price than existing alternatives.
