Capacitive Type Transducer Review
Capacitive-type transducers, illustrated in Figure A-1, consist of two flexible conductive plates and a dielectric. In this case, the dielectric is the fluid.
Figure A-1
As pressure increases, the flexible conductive plates will move farther apart, changing the capacitance of the transducer. This change in capacitance is measurable and is proportional to the change in pressure.
