Mechanical girder load test, Slovakia
Girder was loaded constantly and
exposed to high corrosive
environment. The aim of this testing
was to verify which of actually
available monitoring technologies will
provide long term stable measuring
results in this environment.
Our FBG based sensors (FFA-01)
succeeded to survive this harsh
environment for the entire length of
testing with very stable measuring
results confirming the suitability of
fiber-optic technology for such long
term monitoring projects in any
industry.
