IoT connectivity for isolated assets

| By Mary Page Bailey and Gerald Ondrey

The Wilsen.valve and Wilsen.node internet of things (IoT) sensor nodes (photo) wirelessly transmit data from spatially isolated assets to the network communication system. The battery-operated devices record measurement data, position data and the status of the connected sensors and wirelessly transmit this information to the IoT system via LoRaWAN, allowing monitoring and associated follow-up actions to be automated with minimal effort. Up to two inductive dual sensors for valve position feedback can be connected to the Wilsen.valve. A single device can therefore report the position of up to two 90-deg manual valves. Various types of two-wire sensors can be connected to the Wilsen.node. Typical applications for this version include object detection tasks, such as monitoring manhole lids and gates. — Pepperl+Fuchs SE, Mannheim, Germany
