ATEX-certified energy harvesting power
source
Perpetuum has launched the intrinsically safe ATEX approved microgenerator version of the industrial PMG17 vibration energy harvester, for safe sensor working in Zone 0, 1 or 2 environments
The PMG17 is a microgenerator that enables wireless, battery-free sensing for condition monitoring and asset management applications: it 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

Energy harvester generates more power
Following the success of its PMG7 microgenerator, Perpetuum has launched its next generation microgenerator, PMG17, which generates more power from low levels of vibration
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 customers are now free to incorporate energy harvesting technology (and hence avoid the need for any batteries) in wireless sensor nodes for use in 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 at Perpetuum.
Operators in hazardous industrial environments can now deploy energy harvesters in their wireless plant monitoring equipment, which is allowing them to significantly reduce down-time and save thousands of pounds.
The PMG17 transforms the kinetic energy of machine vibration into electrical current, which is sufficient to power complete wireless sensor nodes, including sensors, microprocessors 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 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 from 2-4 October on booth 2926.
The demonstration will show the transmission of motor condition and temperature data over the 802.15.4 wireless protocol.
