Modified dual diaphragm pressure sensor |
摘要 |
A device for sensing pressure using two flexible diaphragms in which an additional element is added to promote rolling contact of the diaphragm. One embodiment aligns the flexible diaphragms in a non-parallel alignment such that deflection of one flexible diaphragm will roll with respect to the other to provide increased linear capacitive response. In another embodiment a non-conductive spacing element is positioned between the diaphragms to permit rolling contact upon displacement of a diaphragms. These devices are capacitive pressure gauges. One additional embodiment includes a cantilever hinge and rigid polymer disc to convert one diaphragm into a linearly deflecting diaphragm.
