FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring technology and can be used to measure cable-stayed structures. Essence of the invention is that the pre-tensioned cord is pinched between two clamps of a material with a high coefficient of friction, for example rubber. Using the immersion positioning system, made in the form of a gear-helical gear, the indenter is fed to the cord before touching, but so as not to introduce additional load on the cord. In the center of the cord, using a release mechanism releasing the cocked spring, mounted on the pointer movement indicator, the load is applied and the deflection is measured. Strength of the pre-tension cord is determined by the formula.
EFFECT: technical result consists in creating a portable device for determining the tension of the cords, which ensures a reduction in measurement errors.
