Axial and Diameteral Strain Measurement
When testing cylindrical specimens of soil or asphalt, axial diameteral deformations can be measured at the center of the specimen, away from end effects introduced by the loading platens. This enables accurate determination of modulus and Poisson’s ratio. Standard size ranges of 2.8 to 6 inches plus metric sizes are available.
Triaxial Cells
Interlaken’s universal system for soils and asphalt can be used with a wide variety of triaxal cells. It will easily interface with triax cells from several different manufacturers and suppliers as well as Interlaken's large diameter triaxial cell.
Platen
to Platen LVDT's
Interlaken's platen to platen lvdt's are typically used with very soft and unstable soil samples.
