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.

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.
