FIELD: measuring equipment.
SUBSTANCE: invention relates to a device for thread measurement (1), comprising a holding holder with possibility of disconnection of pipe (2), at that on end of pipe (2) there is formed thread (1), as well as first optical measuring section (5) with optical sensor (5a). At that, optical measuring section (5) is located on manipulator (3) for movement of optical measuring section (5) relative to pipe (2). At the same time, optical measuring section (5) can be adjusted by turning about first positioning axis (S1) relative to axis (A) of thread (1), wherein manipulator (3) is located second optical measuring section (5) with second optical sensor (5a). In general, optical measuring sections (5) together form measuring channel (4) for simultaneous measurement of opposite sides of thread (1). Besides, measuring channel (4) is made with possibility to turn by means of manipulator (3) relative to axis of thread (A) around at least second positioning axis (S2) so that free orientation of measuring channel (4) is provided in range of solid angles.
EFFECT: high accuracy of monitoring quality of thread measurement.
