|Type||Tension Proving Ring|
|Packaging Type||Protective Wooden Case|
We offer high quality Compression Proving Rings. These Proving Rings are used for load measurements and are used in the outfits of a number of Soil/Cement & Bitumen Testing Equipments like Direct Shear Test Apparatus, Triaxial Shear Test Apparatus, C.B.R. Test, Unconfined Test, and Marshall Test etc. Compression Proving Rings 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 centre of the proving ring. The dial gauge readings thus obtained versus laod applied enable the operator to find out unknown load, just by noting the dial gauge reading for the unknown load.
Proving Rings, from 50kg to 100,000k9 capacity provided with 112 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 25000kg (or 25 Tones) are not thus threaded. Each ring is individually calibrated and supplied with works calibration chart and a carrying case.
Calibration Charts from Standa rd 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 50 kgf to 200000 kgf are available.
