Extended power module life for wireless transmitters
Emerson Process Management is using Perpetuum’s Vibration Energy Harvester and Intelligent Power Module solutions to achieve energy harvesting within its Smart Wireless transmitters.
Energy harvesting converts un-used 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. It is expected that other wireless Emerson transmitters will use the technology in the future.
“Energy harvesting delivers significant economic benefits, not just from avoiding power module replacement costs, but also by eliminating unnecessary maintenance logistics and relieving skilled labour to concentrate on more essential plant operations,” said Bob Karschnia, vice president of Smart Wireless Solutions for Emerson Process Management.
Perpetuum’s Intelligent Power Module holds the same form, fit and operational capability as Emerson’s current Smart Power Module, with the operational enhancement of enabling Emerson’s wireless transmitters to accept multiple forms of external power.
This energy harvesting solution is 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.
