MULTI-ROLLER DYNAMOMETER AND TEST METHOD

In a dynamometer, a multi-roller sheave (37) is positioned between a cable (28), or other elongate element, supply and the cable destination so that the cable rolls over the multi-roller sheave (37). The center axis of the cable changes direction from one side of the multi-roller sheave to the other...

More Information
Summary:In a dynamometer, a multi-roller sheave (37) is positioned between a cable (28), or other elongate element, supply and the cable destination so that the cable rolls over the multi-roller sheave (37). The center axis of the cable changes direction from one side of the multi-roller sheave to the other side. Tension in the cable causes the multi-roller sheave to move and consequently stress a strain gauge. A signal produced by the strain gauge is amplified into a signal that accurately indicates the tension in the cable. Friction and wear between the cable and the dynamometer (34) are eliminated for all practical purposes. Very accurate readings of tension are obtained.
