Calibration and Uncertainty Evaluation of Steel Wire Rope Tension Meter

The fatigue and wear of the steel wire rope led to the reduction or loss of its bearing capacity, at present, the tension of the steel wire rope was measured and monitored by testing organization through tension meter. The basic structure and working principle of the tension meter for steel wire rope were analyzed to study the calibration method and measurement characteristic of the tension meter. The lever-type force testing machine was used as the standard device, the laboratory calibration of the steel wire rope tension meter was realized by changing the standard force value with matching weights. The uncertainty of indication error of wire rope tension meter was evaluated, and the expanded uncertainty was 0.17%FS.
