Wireless train sensor harvests energy

Energy harvesting firm Perpetuum has gone to LPRS for radios for its real-time railway bearing monitoring system.

Changing vibration and temperature patterns from bearings can warn they are becoming worn, and the Perpetuum sensor system provides vibration data for long term failure prediction and temperature data for short term…

Integrated sensor designs get benefit of fieldbus

Despite developments in sensor technology, the integration of a sensor within a larger systems device often results in a simple digital on/off signal. Whilst many applications would find this adequate, there is so much more that is possible by integrating the operation and configuration of sensors into the machine…
