System and method for sensing pressure

A differential pressure sensor for use in a pressurized environment, comprising:

• a housing having a first side and an opposing second side;
• a membrane layer substantially surrounded by the housing, wherein the membrane layer has a covered portion isolated from the pressurized environment and an exposed portion exposed to the pressurized environment;
• at least one resonating device disposed within the covered portion of the membrane layer;
• and
• sensing circuitry coupled to the at least one resonating device and configured to detect changes in oscillation of the at least one resonating device indicative of deformation in the membrane layer.
