Live Demonstration: Energy autonomous wireless valve leakage monitoring system with acoustic emission sensor

摘要

This demonstration will present an industrial process monitoring system developed at VTT and piloted at Metso Flow Control Oy for the application of valve leakage detection. The system applies a MEMS based acoustic emission sensor for the detection of valve micro fractures manifested as acoustic emissions in high-pressure valves. A whole system is developed including an asynchronous ultra-low power wake up radio and energy harvesters for both the sensor nodes and base station device giving a fully energy autonomous solution [1].
