PRESSURE GAUGE Russian patent published in 2015 - IPC G01L9/00 

FIELD: measurement equipment.

SUBSTANCE: pressure gauge comprises a measurement unit, an elastic membrane, and at least one oscillating elastic element (resonator) connected to the membrane as capable of variation of its tension in accordance with membrane deformation. The membrane is made as round in plan and at least with one concentric corrugation (or several concentric corrugations), covered with a circular resonator on its edges from magnetic material or with an additional magnetic element (elements). The measurement unit comprises an electromagnet and is made as capable of stimulation of resonator oscillations and recording of their oscillations.

EFFECT: simplified design and technology of pressure gauge manufacturing.
