    Masonry moisture measurement using the distributed temperature sensing system

  • Original language description

    Distributed temperature sensing systems (DTS) are based on the principle of time-domain reflectometry where an optical fiber acts as a temperature sensor. DTS is capable of measuring the temperature along the optical fiber using the nonlinear phenomenon referred as Raman scattering. The biggest advantage of such sensing system is the use of an optical fiber itself as a sensor which gives the benefits of electromagnetic interference immunity, low sensor cost, measurement distances up to 10 kilometers and the safe use in flammable and corrosive environments. Fiber optic DTS can be therefore used in the environments and processes in which the application of conventional sensors is impossible. This article discusses the use of DTS for the moisture measurement in the masonry. In structures with built-in optical fiber, the immediate detection and location of moisture are possible. To perform the measurements an experimental brick wall has been built and between each wall layer the optical fiber was placed. The wall was built in stainless steel tub with a drain valve and was placed on a mobile trolley. The dimensions of the wall were 106 x 100 x 30 cm. The actual measurements were carried out in two stages. In the first, the tub was filled with water and the temperature change associated with the gradual increase of moisture inside the wall was measured. This measurement lasted until the saturation which was the time when the wall has no more moisture to adopt. The second stage then examined the evolution of the temperature inside the wall during gradual desiccation until the time when the temperature inside the wall was uniform between all layers. © COPYRIGHT SPIE.
