FIELD: measuring equipment.
SUBSTANCE: group of inventions relates to measuring equipment for determination of radii of curvature of long-length tubes. A device for measurement of radius of curvature of a long-length pipe includes three sensors located at certain distances one after the other along a longitudinal axis of the tube under study. The device consists of a case, in which all three sensor are placed, among which the middle sensor is located in the middle part of the case at a random distance from one of edge sensors, and an additional sensor is installed opposite the middle sensor. Sensors are part of distance control units, each of which also includes thrust, at one end of which a roller is installed, a guide, and a spring, one support end of which rests on the other end of thrust, and the second one rests on the inner surface of the case or another part fixed from movements. An additional distance control unit is installed opposite the middle distance control unit. The device includes at least one length meter connected to the roller, or the middle roller, or an additional roller.
EFFECT: increase in the accuracy of measurements of radius of curvature of a long-length tube.
