ARRANGEMENT FOR MEASURING LINEAR SIZES Russian patent published in 2006 - IPC G01B13/10 

FIELD: the invention refers to measuring technique and may be used for checking linear sizes in a broad diapason.

SUBSTANCE: the arrangement for measuring linear sizes has a pneumatic measuring device and an measuring unit which includes two measuring elements with measuring surfaces having elastic connection and a measuring nozzle installed in the first of the elements. The face surface of the nozzle form with measuring surface of the second element a measuring gap. At that the second measuring element is fulfilled in the shape of a spring formed by contrary cuts made in chess-board order perpendicular to the measuring line. The measuring nozzle is installed with possibility of displacement in the flatness perpendicular to the measuring line.

EFFECT: increases diapason of measuring at conservation of accuracy.
