FIELD: measurement equipment.SUBSTANCE: invention relates to measurement equipment, in particular, to devices for measurement of profile of surfaces of low-modular viscoelastic sheet materials of light industry, namely, man-made and natural leathers, etc. A device to detect profile of materials in deformed condition, comprising a base, a counting unit, a locating element, installed as capable of rotation around its axis, differing by the fact that the locating element is made in the form of a semi-cylinder with a hollow semi-cone and two limiting plates to fix a sample; the device comprises an additional counting unit fixed on the semi-cylinder, to detect bending radius of the investigated sample, arranged in parallel to the semi-cone guide, at the same time the main counting unit is made as combined, capable of displacement along the axis of rotation of the locating element and comprises a strain gauge motion sensor and a digital optical microscope.EFFECT: device makes it possible to study hidden defects of natural leather and man-made materials, to determine variation of material relief under bending deformation.2 cl, 1 dwg |
