Railway Metrics and Dynamics’ PMU sensor used in new research study at KTH
Sensor monitoring of railway bridges can save society a lot of money. Researchers at KTH are now investigating whether sensors from Railway Metrics and Dynamics can provide the same results as permanently mounted sensors – at a fraction of the cost.Sensor monitoring of railway bridges allows real-time monitoring of the condition of bridges, enabling timely maintenance to maximise their lifespan. The problem is that a complete fixed sensor system costs between SEK 100 000 and 200 000 per bridge. On the Botnia line between Uusimaa and Umeå, to give an example, there are 147 railway bridges.
