DEVICE AND METHOD FOR NONCONTACT MEASUREMENT OF CURVATURE OF LONG OBJECT Russian patent published in 2012 - IPC G01B11/00 B61K9/08 

FIELD: machine building.

SUBSTANCE: device and method is intended to be used at measurement of curvature through certain base length of object (2t), for example per 1 running metre and maximum curvature through the whole length of the object. The basis of measurements is proximity sensors. Condition of measurements is straight-line movement of the object. There can be deviations at movement in the form of transverse offsets and vibration. In order to relate measurements to length and to compose the object curvature chart, speed sensor is used. Enough number of sensors will be log₂(L/t)+2 sensors. They are located at distances of (t, t, 2t, 4t, 8t, 16t,…) between each other, where t - half of the base distance for curvature measurement.

EFFECT: device allows reducing the number of involved sensors at curvature measurement.
