MANOMETRIC SPRING Russian patent published in 2004 - IPC

FIELD: measuring engineering.

SUBSTANCE: cross-section of the device is made of two conjugated inner and outer working sections. The inner section is bellows-shaped. The corrugations of the bellowsare arranged along the vertical axis of symmetry of the cross-section and obey the condition h_B > c_B, where h_B is the height of the corrugation of the inner working section, c_B is the width of the corrugation of the inner working section. The outer working section can be elliptical, flat-oval, or eight-shaped and obey the condition a_H > b_H, where a_H is the greater axis of the outer working section, b_H is the smaller axis of the outer working section. The outer working section can be also bellows-shaped, and its corrugations are arranged along the horizontal axis of symmetry of the cross-section and obey the condition h_B < c_H, where h_H is the height of the corrugations of the outer working section, c_H is the width of the outer working section.

EFFECT: enhanced sensitivity.
