Wireless applications that require continuous monitoring to detect energy savings, unsafe, or other avoidable conditions and that must avoid serious maintenance problems are well suited for energy production. Steam trap monitoring is an excellent example of this type of battery-free detection.
The U.S. Department of Energy (DOE) reports that about 20 percent of the steam leaving the central boiler of a typical facility is leaking in space heating applications. lost due to steam traps. Although these losses also occur with operating traps, the DOE estimates that 15 to 30 percent of steam traps that are not regularly inspected and maintained fail. The solution is a continuous monitoring system that uses battery-free sensors to provide real-time warnings and alarms through the cloud without the need for manual monitoring or requiring battery replacement.
This analysis leveraging Hill Air Base to install Everactive’s battery-free sensors in its steam trap and machine condition monitoring systems. These sensors continuously monitor 650 steam traps and 550 rotating machines at the base, which covers 1,700 facilities on one million hectares.
Everactive sensors operate solely on the small amount of energy collected, completely eliminating batteries. Wireless sensors continuously transmit data up to a distance of 250 meters to the organization’s IoT (Internet of Things) gateways and then to the cloud. The data analyzes performed provide useful information and guidance for facility maintenance and reliability professionals
