COMBINED MANOMETER SPRING PROVIDED WITH INSERTIONS Russian patent published in 2006 - IPC G01L7/04 

FIELD: measuring technique.

SUBSTANCE: combined manometer spring can be used in devices for measuring pressure, robotics systems, which work under conditions of vibrations and in power mode. Manometer spring has several tubes connected together. Any tube has constant thickness of wall and corresponding relation of half-axes of cross-sections. Tunes are connected together by means of elastic insertions. Elastic insertions are made of material which has module of elasticity being smaller than that one of material of tubes to be connected.

EFFECT: improved sensitivity; increased strength of spring.
