DEVICE FOR MEASURING SURFACES MACRO ROUGHNESSES Russian patent published in 2016 - IPC G01B21/30 G01C9/16 

FIELD: measuring equipment.

SUBSTANCE: device for measuring macro roughnesses surfaces can be used in hydropower control macro roughnesses, taper and deviation from the horizontal plane mirror surfaces disc thrust bearings of hydroelectric. Device for measuring macro roughnesses surfaces, comprising mounted horizontally and in parallel above one another rigid rectangular plates fixed together by vertical uprights disposed on the outer side of each plate at the corners three support adjustable legs installed at the inner side of the bottom plate two sensor inclination angle, the axes sensitivity are mutually perpendicular and parallel to the adjacent side of the plate and fixed by means of removable alignment ring on one of the plates with its outer side magnet, the center of which is located inside the right-angled triangle formed by the three bearing adjustable feet at the median from the vertex of the right angle.

EFFECT: technical result is to increase the accuracy of measurement macro roughnesses by measuring the angular displacement in the coordinate system associated with the survey surface, expanding the functionality of the device.
