CRD-patchglueable FBG strain sensor |
 |
product description:
CRD-patch is a Fibre Bragg Grating sensor designed to measure the strain imposed to it by its substrate. The sensor is embedded inside a composite filament made by carbon fibres, in the selected dimensions. CRD-patch is then glued via epoxy resin on the area of interest. The sensor follows the surface's displacements.
CRD-patch can be installed on surfaces and elements when the installation of rigid anchors is prohibited (due to aesthetic reasons, material or shape restrictions, etc). It is ideal for installation on concrete or steel structural members.
