MANOMETER Russian patent published in 2006 - IPC G01L7/04 

FIELD: instrument-making industry, in particular, engineering of measuring equipment, possible use for measuring environment pressure.

SUBSTANCE: device has holding base, Bourdon tubular spring, bent along circle arc, ending with end piece sealing it on one end and held hermetically in holding base by another end, and adjusting assembly. Adjusting assembly consists of base, one portion of which is rigidly held on holding base, and another portion, positioned on external side of tubular spring, contains threaded aperture. Its axis is positioned along direction of circle arc radius, along which longitudinal axis of tubular spring is bent, or those of adjusting screw being in aforementioned threaded aperture. Base of adjusting assembly is made non-deformable under pressure on it through adjusting screw of tubular pipe. Axis of threaded aperture is positioned from place of connection of tubular spring in holding base within limits of angle, determined by expression: (0,10-0,15)γ₀, where γ₀ - central angle of tubular spring, counted from place of intersection of longitudinal axis of spring with boundary of holding of tubular spring in holding base.

EFFECT: simplified construction, decreased dimensions and simplified adjusting.
