Press Release Summary:
Intrinsically safe PMG17 transforms kinetic energy of machine vibration into electrical current sufficient to power complete wireless sensor nodes, including sensors, micro processors, and 802.15.4 transceivers. Designed for safe working in Zone 0, 1 or 2 environments, microgenerator carries ATEX EC-Type Examination Certificate and IECEx Draft Certificate of Conformity for use in hazardous oil, gas, chemical, and petrochemical environments where flammable gases may be present.
Original Press Release:
Perpetuum's PMG17 Energy Harvester is ATEX-Certified for Hazardous Environments
Southampton, UK, October 2nd 2007 - Perpetuum launches the intrinsically safe ATEX version of the industrial PMG17 vibration energy harvester, for safe working in Zone 0, 1 or 2 environments. The microgenerator that enables wireless, battery-free sensing for condition monitoring and asset management applications has been given an ATEX EC-Type Examination Certificate and a IECEx Draft Certificate of Conformity. These certificates, when combined with pending QA certifications, will allow Perpetuum to supply the PMG17 to its customers with Ex ia IIC T4 markings.
The new intrinsically safe PMG17 energy harvester has been designed and certified for use in hazardous oil, gas, chemical and petrochemical environments where flammable gases may be present. Perpetuum's customers are now free to incorporate energy harvesting technology (and hence remove batteries) into wireless sensor nodes for use in these hazardous areas for the first time.
"This certification is an important step forward for our customers with hazardous environments," says Dr Stephen Roberts, Technical Manager, Perpetuum. "Operators in hazardous industrial environments can now deploy energy harvesters in their wireless plant monitoring equipment, allowing them to significantly reduce down-time and save thousands of dollars.
The PMG17 transforms the kinetic energy of machine vibration into electrical current, which is sufficient to power complete wireless sensor nodes, including sensors, micro processors and 802.15.4 transceivers. The ATEX-approved PMG17 microgenerator benefits from the same rigorous design and build processes that are a feature of all Perpetuum's microgenerators, making it a cost-effective and reliable solution for hazardous environment applications.
A fully-working wireless sensor node demonstration system powered by a PMG17 will be in operation at ISA Expo in Houston, Texas 2-4 October in booth 2926 (http://www.isa.org/expotemplate.cfm). The demonstration will show the transmission of motor condition and temperature data over the 802.15.4 wireless protocol.
