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.
