FIELD: measurement equipment.
SUBSTANCE: device includes a retaining pin, a lever element for creation of bending of the measured item, and electronic unit arranged in an extended beam with a built-in sensitive element in the form of a strain gauge and with three supports - a central one and end ones. Central support has moving structure and is capable of being moved perpendicular to longitudinal axis of the measured item. A retaining pin and a lever element is installed on central support. End supports have fixed structures. End supports and central support have the possibility of working contact with the measured item on one of its sides from longitudinal axis.
EFFECT: possible measurement of tension force without preliminary determination of diameter of the measured item; shortening of measurement time and reduction of measurement error.
