Claim 0:
1. A method of determining a pressure differential, the method comprising:
providing a pressure sensor comprising:
a substrate defining a first substrate surface and a second substrate surface;
a first pressure sensing assembly attached to the first substrate surface and configured to detect a first pressure force associated with a first volume of fluid, wherein at least a portion of the first substrate surface to which the first pressure sensing assembly is attached is fluidly isolated from the first volume of fluid by a first force transmitting member retainer, wherein the first force transmitting member retainer extends from the first substrate surface; and
a second pressure sensing assembly attached to the second substrate surface and configured to detect a second pressure force associated with a second volume of fluid, wherein at least a portion of the second substrate surface to which the second pressure sensing assembly is attached is fluidly isolated from the second volume of fluid by a second force transmitting member retainer, wherein the second force transmitting member retainer extends from the second substrate surface; and

determining a pressure differential based at least in part on the first pressure force and the second pressure force,
wherein the first substrate surface and the second substrate surface define opposing ends of a thickness of the substrate.
