Individual tensiometer for measuring tension of racket string, has flexible strip deformable by rotation of base body around axis transverse to string and parallel to median plane, and measuring unit measuring flexion deformation of strip

摘要

The tensiometer (1) has a stressing component (2) with support elements e.g. studs or fingers, positioned on two sides of a racket string (9). An elongated deformable element i.e. flexible strip (3), connects an ellipsoidal shaped base body (10) to the component. The strip is deformable by rotation of the body around an axis transverse to the string and parallel to a median plane passing between the support elements, at an overlapping state of the support elements on the string. A measuring unit i.e. extensometer (4), measures flexion deformation of the strip. An independent claim is also included for a method for determining tension of a racket string.
