Proving Rings _ Compression Type: 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, CBR Test, Uncontained Test, and 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 is mounted on brackets clamped to the ring body. The dial gauge is held perfectly rigid without the remote chance of shifting due to inadvertent shocks or pressures exerted on it. The dial gauge plunger rests on an adjustable anvil. Proving Rings, from 50 kgf to 1,00,000 kgf capacity provided with 1/2 inch B.S.F female threads. Loading bosses and a loading ball nipple and steel ball are supplied with each ring. Rings of capacity over 25000kgf (or 25 tonnes / 250 kn) are not thus threaded. Each ring is individually calibrated and supplied with works calibration chart and a carrying case.

Calibration charts from Standard Laboratories for the Proving Rings ordered are also available at extra cost.
All Proving Rings are Integral Type.
