Proving Ring

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, Triaxil Shear Test Apparatus, C.B.R. Test, Uncontained Test, and Marshall Test MTC.

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.

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  remotest  chance  of  shifting  due  to  in 
       advement shocks or pressures exerted on it.
• The dial gauge plunger rests on an adjustable anvil.
• Proving Rings, from 50 kg to 1, 00,000kg capacity provided with 1/2 inch B.S.F femal threads.
• Loading bosses and a loading ball nipple and steel ball are supplied with each ring
• Rings of capacity over 25000kg (or 25 Tonnes) 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.
• Integral type Compressive Proving Rings of different  capacities from 50kgf to 200000kgf are 
       available.
