PROVING RING-COMPRESSION TYPE-2.5 KN - WITHOUT DIAL GAUGE

Applications

Used for load compression measurement applied by the testing machine and to calibrate the testing machine.

Construction Details

These proving rings are made out of special steel, carefully forged to give maximum strength & machined to give the highest sensitivities commensurate with high stability and to ensure long life and accuracy. The proving ring is integral type viz.  the loading (outside) bosses are forged integral with the ring body. This ensures that there is no possibility of abutment shift and consequent loss of accuracy in reading that always exists in rings with bolted abutments. The dial gauge and anvil are mounted on U‑brackets clamped to the ring body by Allen set screws.

The dial gauge is fitted with a special back cover and threaded bush, which does not permit any shift from the original diametric alignment, coaxial with the loading boss centers, that is set at the factory before calibration. The boss faces are ground and polished and are lane parallel to within 0.02mm  total D.T.I. run‑out. Caps are provided for use when loading in compression.  Repeatability is as  stipulated in IS : 4169‑1967. The ring is supplied complete with dial gauge and our own calibration chart, packed in polished wooden boxes.

Supplied complete in polished wooden carrying case, fitted with Dial gauge of 0.002mm x 5mm. With our own calibration report and traceability

The Calibration certificate from NCB/RTC or any other approved Laboratory can be provided at an extra cost at the rate prevailing at the time of supply.
