In France, rail temperature is closely monitored during summer season. Above a specific threshold, onsite inspections are planned to keep watch on the thermal expansion of the rail. To date, rail samples equipped with an alcohol thermometer are disposed in risk areas. The maintenance agent comes onsite to check the temperature.
INTESENS has developed a geolocated temperature sensor integrated to the rail sample. The hardened sensors (resistant to vibration, temperature changes, humidity…) are laid near the railroad.
Thanks to the rail temperature solution, the agents can monitor the temperature on the IDIAG Web platform. In case of high temperature, they are notified in real time.
