DEVICE FOR MONITORING OF GEOMETRIC PARAMETRES OF CYLINDRICAL ITEMS WITH THREADED SURFACE Russian patent published in 2010 - IPC G01B11/30 G01B3/48 

FIELD: physics.

SUBSTANCE: device comprises base, on which there is a unit installed for positioning of controlled item, coordinate table arranged with the possibility of displacement along longitudinal axis of controlled item and connected to detector of linear displacement and electric drive of linear displacement, cylindrical body, scanning unit, having the first fork and facilities for information pickup, detector of angular displacement and electric drive of angular displacement. And also facility of information processing arranged in the form of personal computer (PC), unit of axes matching arranged on base, on which coordinate table is installed. Cylindrical body is arranged with the possibility of rotation around longitudinal axis and is installed in two bearings on coordinate table, scanning unit has the second fork installed symmetrically to the first fork and holder of forks with mechanism of distance adjustment between forks.

EFFECT: expansion of device functionality, provision of possibility for device operation in industrial environment.
