Abstract: A capacitance manometer is disclosed which includes at least one electrode structure having an inner electrode structure and an outer electrode structure separated by at least one gap, at least one flexible diaphragm having at least one conductive material positioned thereon or integrated therein may be positioned in movable relation to the electrode structure and in proximity to the electrode structure, and at least one non-planar baffle having an inner baffle structure and an outer baffle structure separated by at least one baffle orifice positioned distantly from the electrode structure proximate to the flexible diaphragm.

Abstract: A pressure sensor may measure gas or liquid pressure. A chamber may have an inlet that receives the gas or liquid. A flexible diaphragm may be within the chamber that has a surface exposed to the gas or liquid after it flows through the inlet. A pressure sensor system may sense changes in the flexible diaphragm caused by changes in the pressure of the gas or liquid. A pressure-insensitive sensor system may sense changes in the flexible diaphragm that are not caused by changes in the pressure of the gas or liquid. The pressure-insensitive sensor system may be insensitive to changes in the flexible diaphragm caused by changes in the pressure of the gas or liquid.
