Courtesy: Emerson, PerpetuaEmerson has adopted Perpetua's Power Puck thermoelectric energy harvesters are designed to convert ambient heat commonly released in industrial processes into electricity for powering Rosemount wireless transmitters. The Power Puck energy harvesting solution is useful for wireless devices in power intensive applications where a conventional power module may require replacements more frequently. The Power Puck thermoelectric energy harvester provides continuous, reliable power for the life of the transmitter and includes an intrinsically safe power module for back-up power. A heat source is all that is required to fully power wireless transmitters at their fastest update rate. Configurations allow connections to most heat sources, including flat and curved surfaces with temperatures up to 449 C (840 F). Power Puck solutions are also classified for use in hazardous areas.
