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
