From theory to practice! Below is a description of one of the many tests conducted in our research field. The underground pipe was buried 1 m below ground level. Both pipe and surrounding ground were equipped with different types of…
Distributed temperature sensing (DTS) is gaining increasing popularity across various applications. One of the most promising areas is geothermal energy, which focuses on harnessing the heat stored within the Earth. We had a pleasure of cooperating with Państwowy Instytut Geologiczny…
In our applications involving concrete structures, understanding the resistance of sensors to an alkaline environment is crucial for ensuring long-term, high-quality operation. We placed selected sensors in a 5% NaOH (sodium hydroxide) bath for over 8 months. Measurements showed no…
On April 23-25, we took part in InfraDays. On the second day, during the bridge session, the event participants had the opportunity to see our presentation “Fiber optic sensors – a breakthrough in monitoring the safety of structures.” We would…
The recent floods unfortunately remind us of the need to monitor and diagnose safety-critical infrastructure such as dams, levees and reservoirs. To assess their technical condition after these extreme events, we need effective diagnostic solutions that can provide a comprehensive…
Thermal compensation is one of the key aspects in long-term DFOS-based monitoring. To do it well, we need to know: All the above aspects have been discussed by our team in the latest publication, which shows not only laboratory research,…
Our latest implementation. New five-span bridge, with a total length of over 267 m, was constructed using the incremental launching method ILM. The cross-section is a prestressed box with a height of 3.5 m. It was decided to equip the…
One of our DFOS & DAS engineers – Szymon Długosz recently visited the Mont Terri Project laboratory, located near St-Ursanne in the canton of Jura. It is used to study the Opalinus Clay, a host rock for a proposed future…
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…
Check out our new open-access article written by the members of our team available in Elsevier’s Measurement! – “Structural concrete measurements: New distributed approach for standard specimens”. Do you know how to…
