Energy harvesting solution for transmitters
Emerson Process Management is making energy harvesting a reality for its Smart Wireless transmitters through the use of Perpetuum’s vibration energy harvester and intelligent power module solutions. Energy harvesting converts unused energy, such as vibration from pumps and motors, into electric energy. Perpetuum vibration energy harvesters provide external power to Emerson’s transmitters, decreasing maintenance by extending the life of the power module.
The Rosemount 3051S wireless pressure transmitter is the first Emerson wireless transmitter capable of utilising this energy harvesting technology. Additional wireless Emerson transmitters will use this technology in the future. This energy harvesting solution is fully certified to FM (Class1 Div1, Groups A, B, C, D), as well as ATEX and IECEx (Zone 0). It is intrinsically safe and classified for use in hazardous areas, thereby reducing potential safety risks to plant personnel.
