Another exciting installation behind us!

This time we equipped the Extradosed bridge managed by Generalna Dyrekcja Dróg Krajowych i Autostrad (division in Łódź) with a hybrid monitoring system. In addition to fibre optic sensors (EpsilonSensor) for periodic readings, we also used vibrating wire sensors and accelerometers for automatic measurements.

Thanks to the sensors used, we can measure:

• distributed strains (DSS) and cracks
• dynamic spot strains
• dilatation displacements
• tilts
• accelerations
• temperatures

We also use a camera to monitor cars and trucks crossing the bridge.

Hybrid systems combine the advantages of distributed measurements with automatic spot gauges. We are looking forward to the first results, which will be interpreted by experts from the Rzeszow University of Technology. The monitoring system was designed by prof. Piotr Olaszek and Artur Sakowski from Instytut Badawczy Dróg i Mostów IBDIM/Road and Bridge Research Institute.
