Abstract
An apparatus for measuring tension in linearly extended flexible material. The apparatus comprises: a support means; a first member having one end attached to the support means; means associated with the first member for engaging tensioned material to impart a bend thereto, thereby causing strain in the first member, such strain being produced by first and second moments, with the first and second moments being separate moments; and means associated with the engaging means for sensing the strain caused in the first member by only the first moment and for generating a signal responsive thereto as an indication of the tension in the material.
Claims14
An apparatus for measuring tension in linearly extended flexible material, said apparatus comprising:
- (a) a support means;
- (b) a first member having one end attached to said support means;
- (c) means associated with said first member for engaging tensioned material to impart a bend thereto, thereby causing strain in said first member, said strain being produced by first and second moments, said first and second moments being separate moments;
- and (d) means for sensing said strain caused in said first member by only said first moment and for generating a signal responsive thereto as an indication of the tension in said material.
