FIELD: machine building.
SUBSTANCE: invention relates to machine building, in particular to sensors for measuring transverse displacements during stretching of samples from fabric-like materials. To fix the sensor to the sample, the sensor has two crocodile-type clamps, the jaws of which at each clamp are located relative to each other at a noticeable angle of 30° up to 90°. Besides, one clamp is rigidly attached to the long, bending-rigid part, the other clamp has a long, bending-rigid base. In the operating state of the sensor, the clamp with the long base can move relative to the first clamp, which is rigidly attached to the long, bending-rigid part. Movable part of the sensor is moved relative to the fixed part of the sensor by means of roller supports, on one of which a pointer indicator is installed, which makes it possible to determine the angle of rotation of this roller support when the sample is stretched. To increase friction forces between roller supports and mating parts, flat rubber parts glued to mating parts are used. Parts of the jaws of the crocodile clamps interacting with the sample are smooth and have a rounded surface.
EFFECT: enabling measurement of transverse displacements during stretching of samples from fabric-like materials, wherein no power source is required.
