FIELD: physics, measurement.
SUBSTANCE: invention is related to metering equipment and is designed for measurement of deformations. Crank-lever indicator tensometer comprises base, fixed and movable supports with distance between them that make the instrument base and are equal to 100 mm, crank lever, scale for measurement of deformations. At that base is arranged in the form of bar with rectangular cross section, and supports are arranged in the form of "П"-shaped prisms. One of supports is fixed on base, and the other is rigidly fixed to crank lever with lever arms ratio of 5:1, which in its turn is connected to base by means of elastic plate installed perpendicular to longitudinal axis of base that serves as hinged joint and provides for more accurate fixation of preset measurement base, and with its free second end. Scale for measurement of deformations is a micron indicator of clock type installed on base, leg of which rests on free end of crank lever.
EFFECT: higher accuracy of measurement due to increased enlargement factor with simultaneous simplification of device design.
