Rebar Strainmeters (Fiber Optic)

Rebar Strainmeters (Fiber Optic)
The 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. The Fibre Optic element employed in this sensor makes it particularly suitable where dynamic measurements…

Temperature Sensors (Fiber Optic)

Temperature Sensors (Fiber Optic)
The Model FP4700 Fiber Optic Temperature Sensors are designed for use in environments where high levels of electrical interference exist or where intrinsic safety is an issue. The FP4700 uses the temperature-dependent birefringence of a specially selected crystal as the temperature transduction mechanism. This crystal does not show thermal creep or aging as with some…

Strain Gages (Fiber Optic)

Strain Gages (Fiber Optic)
The Model FP4000 Fiber Optic Strain Gages are designed for use in environments where it may be difficult to use conventional types of strain gages because of space considerations, high levels of electrical interference or where intrinsic safety is an issue. Measurements of dynamic events are also possible with these gages and the requisite dataloggers.…
