Energy harvesting is used to replace the battery of wireless instruments and sensors with an unlimited, green, sustainable, maintenance-free power supply. As the result of a joint development project between ABB and Micropelt, a WirelessHART temperature transmitter has been equipped with a thermal energy harvesting unit containing two Micropelt Thermogenerators MPG-D651 with a footprint of 6 mm² each. A temperature gradient of 30°C between the sensed medium and ambient air is sufficient to fully cover the power demand of the mesh-networked wireless instrument.
With the April issue, we celebrate the 40th anniversary of IEN Europe. For that occasion we present numerous interesting articles and interviews on technologies that have been groundbreaking over the past decades. An interview with Nexans is on the Evolution of Cables . A technical article by the EMVA on Machine Vision emphasizes the milestones that have been important for the automation industry. A very recent and up-to-date topic, Industry 4.0, is discussed in an Interview with Wibu Systems, a company dedicated to the protection of know-how. IEN Europe April also features a retrospective on Low-voltage Switchgear by Eaton. To celebrate IEN’s 40th anniversary properly, we have a Reader Offer for you, where you can win a high-tech visual IR thermometer. So please celebrate with us and enjoy!
