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 are…

Rebar Strainmeters (VW)
The Model 4911 Rebar Strainmeter is designed for measuring strains in foundations, slurry walls, precast piles, caissons, bridge abutments, tunnel liners, etc. The standard Model 4911 (#4 rebar), known as the “Sister Bar,” is installed alongside structural rebar. Larger models (4911A) are available for welding directly into structural rebar. Where short-term dynamic measurements are to…

Soil Extensometers (VW)

Soil Extensometers (VW)
The Model 4435 Soil Extensometer is designed to be installed, in series, to measure horizontal strain and settlements in earth fill or rockfill dams. The 4435 has flanges on either end, which enable a series of extensometers to be bolted together forming long strings of sensors so that complete profiles of deformation or settlement can…

High Temperature Embedment (VW)

High Temperature Embedment (VW)
The Model 4200HT and 4200HT-T High-Temperature Embedment Strain Gages are similar to the standard Model 4200. However, the Model 4200HT is designed for short-term use at temperatures up to 200°C and the Model 4200HT-T is designed for long-term use at temperatures up to 220°C. They are particularly useful for measurements in autoclaved spun concrete piles.…
