WebThe Model FP4911 Fiber Optic Rebar Strainmeter is designed for measuring strains in foundations, slurry walls, precast piles, caissons, bridge abutments, tunnel liners, etc. The standard Model FP4911 (#4 rebar), known as the “Sister Bar,” is installed alongside structural rebar. WebNov 4, 2024 · Current testing methods are capable of measuring strain near the surface on structural parts, for example by using strain gauges. However, stress peaks often occur within the material and can only be approximated. An alternative strain measurement incorporates fibre-optical strain sensors (Fiber Bragg Gratings, FBG) which are able to … WebOperating Principle TheGEOKON®fiber optic strain gauges are designed for use in environments where it may be difficult to use conventional types of strain gauges … taiwan fried chicken dc
