Abstract
A flat measuring string is disclosed that is formed from a blank of sheet metal (such as a niobium-zirconium alloy), characterized by the provision of bendable or foldable wing flaps arranged at the nodal portions of the string, thereby to permit the connection of nodal masses to the string. In this manner, it is possible to achieve good measurement-technical data, especially, data regarding hysteresis and creepage under load, coupled with extensive freedom in the choice of materials and very economical mass production of the string components. The measuring string is particularly suitable for use in force or distance measurement.
Claims8
A flat measuring string, comprising
- a unitary body member formed by punching from a metal sheet, said body member including
- (a) a flat planar central main string portion (12);
- (b) a pair of flat end portions (14) arranged at the ends of said main string portion, respectively;
- and
- (c) a pair of nodal portions arranged between said main string portion and said end portions, respectively, each of said nodal portions including a flat center portion coplanar with said main string portion and of flat, integral wing portions (18) folded with respect to said center portion about parallel fold lines (18a), respectively.
