Stationary electrode 2 is insulated
from the housing by mica
and ceramic in su latio n 4. The
dielectric of the capacitor consists
of layer 3 of mica and
a layer of air. A change in the
pressure a p p lied to diaphragm
1, the second electrode,
changes the distance between d ia phragm
1 and stationary electrode
2. This changes the capacitance
of the capacitor.
