Pressure sensor

A pressure sensor comprising:

• an electrode assembly including a first conductor, a second conductor, a first dielectric member, a second dielectric member, and an outer housing, a lower surface of the first conductor being substantially coplanar with a lower surface of the second conductor and with a lower surface of the outer housing, the first dielectric member being disposed between the first and second conductors and electrically insulating the first conductor from the second conductor, the second dielectric member being disposed between the second conductor and the outer housing;
• a flexible conductive diaphragm, the diaphragm and the first conductor forming a capacitor, a capacitance of the capacitor being dependent upon a spacing between the diaphragm and the first conductor;
• a spacer disposed between the lower surface of the outer housing and the diaphragm.

A pressure sensor comprising:

• an electrode assembly including an outer housing, a first dielectric member, and a first conductor, the outer housing defining an aperture, at least a portion of the first dielectric member being disposed in the aperture defined by the outer housing, the first dielectric member defining an aperture, at least a portion of the first conductor being disposed in the aperture defined by the first dielectric member, a lower surface of the outer housing being substantially coplanar with a lower surface of the first conductor;
• a flexible conductive diaphragm, the diaphragm and the first conductor forming a capacitor, a capacitance of the capacitor being dependent upon a spacing between the diaphragm and the first conductor;
• a spacer disposed between the lower surface of the outer housing and the diaphragm.
