Measuring humidity and temperature in highly corrosive environments.
In collaboration with a large Australian utility company, and City University London, has piloted a generation of Fibre Bragg Grating (FBG) sensors. The sensors are deployed to measure humidity and temperature in highly corrosive environments.
The novel sensors were originally developed by Lourdes to monitor corrosion in construction industry structures such as railway bridges. The optical fibre technology has many advantages over conventional humidity sensors in terms of weight, connectivity, robustness and safety. The work in Australia was primarily to test the sensors for durability and performance in a harsh environment. Bacteria which cause sewer concrete to corrode require a moist environment to grow, hence the importance of monitoring the humidity in a sewer environment.
A new optical processing laboratory is being commission within the School of Engineering and Built Environment (SEBE) and applications
in the UK construction industry are being explored with the involvement
of the Institute of Sustainable Construction (ISC).
