ABSTRACT:
A tensiometer for measuring tension in a tubular, such as a cable, using segmented sheave assemblies is provided. The precision of a tension measurement, and the bending stress to which the tubular is exposed during the tension measurement, are functions of the effective radii of sheaves comprising the tensiometer. A segmented sheave assembly is much smaller dimensionally than a sheave wheel with the same effective radius. For given operating specifications, the tensiometer comprising segmented sheave assemblies is, therefore, much more compact than a tensiometer comprising conventional sheave wheels.
