The TenCate GeoDetect® geotextile enabled sensor comes in three product configurations:
1. TenCate GeoDetect® is a customizable solution that is created to meet the unique requirements of each individual project. Fiber Bragg gratings (FBG), Stimulated Brillouin Scattering and Raman Scattering are all proven fiber optic technologies that can be built into TenCate GeoDetect®. These technologies measure strain, strain & temperature or temperature only changes in soil structures. Strain as low as 0.02% can be measured with a spatial resolution of 1 m. With the proper software, changes in temperature can be monitored at 0.1oC with a spatial resolution of 1 m.
2. TenCate GeoDetect® S uses Fiber Bragg Gratings (FBG) technology to measure strain and/or temperature in soil structures. Compact and easy to install, TenCate GeoDetect® S is 1 meter wide by 10 meters long. Two FBG optical fibers are embedded onto each TenCate GeoDetect® S strip with 11 FBG sensors strategically inserted onto the two special optical fibers approximately 1 meters apart. Strain measurements as low as 0.02% can be obtained with a spatial resolution of 0.5m. Changes in temperature can also be monitored at 0.1oC.
3. TenCate GeoDetect® S-BR is a solution that uses Stimulated Brillouin and Raman Scattering technology in single mode and multimode fibers to measure strain as low as 0.02% and/or changes in temperature of 0.1oC with spatial resolutions of 1 m at distances up to 20 km with suitable instrumentation. The TenCate GeoDetect® S-BR systemis designed for projects such as oil pipelines, levees, roads and rails. The standard version is a strip 0.76 m wide and 600 m long. Customised versions are possible.
