Bridge Monitoring in Greece Used Six Elastisense Sensor Technology DS Displacement Sensors
The Servia High Bridge is one of the longest bridges in Greece, with a length of 1,372 m. Its construction lasted 3 years and was completed in 1975.
Following recommendations by experts, who were concerned about its stability raising the risk of a possible collapse, the local authorities decided to close down its operation in March 2023 to proceed with urgent restoration works.
The 47-year-old bridge appeared to have cracks widening and it was the aim of the experts to monitor their behavior during and after strengthening works which were based on inspection and evaluation results carried out over the last three years.
For this purpose, our Greek partner NEOTEK supplied a wireless system comprising six ElastiSense Sensor Technology DS displacement sensors installed over major cracks, each connected to an analogue node. A central Gateway receives measurements from the nodes and these are available 24/7 over telemetry to the engineers monitoring the restoration progress.
This is just another example of how Neotek always finds good solutions to complex problems. This is indeed an efficient, yet simple and easy way to monitor bridges and learn about the state they are in.
