Abstract (en)
[origin: WO2011110777A2] The invention relates to an individual tensiometer (1) for measuring tension in a racket string (9), said tensiometer comprising: a grip body (10) and a member (2) for biasing the string (9), both of which can pivot in relation to one another; elastically deformable return means (3) configured to return the grip body (10) and the biasing member (2) in relation to one another into a neutral angular position; means for measuring a value representative of the relative rotation between the grip body (10) and the biasing member (2); and means for calculating the tension in the string as a function of the measured value. The grip body (10) and the biasing member (2) have a first possibility to pivot in relation to one another in a first direction and a second possibility to pivot in relation to one another in a second opposing direction.
