Emerson has adopted advanced thermal energy harvesting as a power source for its wireless products. Power Puck thermoelectric energy harvesters convert ambient heat commonly released in industrial processes into electricity for powering Rosemount wireless transmitters.
Perpetua’s Power Puck energy harvesting solution can be advantageous to wireless devices in power intensive applications, where a conventional power module may require replacements more frequently. The company’s Power Puck thermoelectric energy harvester provides continuous 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 using Perpetua’s Power Puck. Configurations allow connections to most heat sources, including flat and curved surfaces with temperatures up to 840°F/449°C. Power Puck certifications include ATEX, IECEx, USA, and Canada.
"Perpetua’s Power Puck is a convenient, sustainable energy harvesting solution which can be incorporated into a variety of applications, enabling users to decrease maintenance costs,” said Bob Karschnia, Emerson’s vice president and general manager for wireless.
