FIELD: machine building.SUBSTANCE: differential pressure converter includes a housing with two differential pressure sensors dividing the inner cavity of the housing into three chambers, two of which are located on the housing ends and serve for connection to pressure sources, and the chamber located between differential pressure sensors is filled with liquid with known physical properties. The chamber between differential pressure sensors has a medium divider with a movable partition wall, which is hydraulically connected to one of the chambers, which serves for connection to the pressure source.EFFECT: improving measurement accuracy of pressure difference, reducing dimensions of measuring devices and enlarging the area of their application.4 dwg, 11 cl |
