Emerson has announced the adoption of 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 is especially advantageous to wireless devices in power intensive applications, where a conventional power module may require replacements more frequently. The 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 using the Power Puck. Configurations allow connections to most heat sources, including flat and curved surfaces with temperatures up to 449 °C. Power Puck solutions are intrinsically safe and classified for use in hazardous areas. Certifications include Atex, IECEx, USA, and Canada.
