Proving ring

Description

We are manufacturer,supplier of compression proving rings.Proving rings are used for load measurements and are used in outfits of a number of soil/cement bitumen testing equipments like direct shear test apparatus, triaxial shear test apparatus, c.B.R. Test, uncontained test, marshall test etc.They are made out of special steel carefully forged to give maximum strength and machined to give highest sensitivity combined with stability to ensure long life and accuracy.When compressive or tensile load is applied within the elastic range, the proving rings get temporarily deformed. This deformation is measured by a sensitive dial gauge fixed co-axially at the center of proving ring. The dial gauge readings thus obtained versus load applied enable the operator to find out unknown load, just by noting the dial gauge reading for unknown load.The proving rings have high elasticity and on removing load they regain their original shape provided they are loaded in their elastic limits. Salient features a dial gauge and plunger anvil are mounted on brackets clamped to the ring body. The dial gauge is held perfectly rigid without the remotest chance of shifting due to inadvertent shocks or pressures exerted on it.
