METHOD FOR MAKING MANOMETERS Russian patent published in 2005 - IPC

FIELD: measuring equipment.

SUBSTANCE: coordinates of center of aperture of flat projection of end piece of tubular spring and length of traction, connecting by joints end piece of tubular spring to tail piece of toothed sector, are determined by averaging these parameters for previously adjusted manometers of current type, for which individual selection of coordinates of centers of apertures for aforementioned joints was performed, and these are set as permanent for new manometers. Determining of coordinates of aperture center in tail piece of toothed sector of each new manometer is performed at manometer assembly, where traction and cover are absent, at two selected values of environment pressure, within limits (0-0,2)P_max and (0,8-1,0)P_max, where P_max - maximal environment pressure measured by manometers of current type. For first selected pressure of environment, tail piece of toothed sector is set in first position, appropriate for first selected pressure, and from aperture center of flat shelf of end piece of tubular spring at tail piece first arc of circle is drawn with radius, equal to traction length. Then to manometer assembly second selected environment pressure is directed, tail piece is turned to second position with arc applied to it, which position is appropriate for second selected environment pressure, and at tail piece second arc is drawn of same radius from flat shelf center, moved to second position. Point of intersection of two arcs is taken as center of aperture of tail piece of toothed sector, wherein second joint is positioned.

EFFECT: simplified construction.
