ABSTRACT:
A pressure sensor includes a diaphragm assembly with a pair of diaphragms joined together along a rim and having spaced apart centers to form a cavity between them. A pressure input applies a pressurized fluid to external surfaces of the diaphragms. The diaphragm assembly is connected to a mounting block along a tab leaving the remainder of the diaphragm free from solid mounting. Deflection of the diaphragm assembly is sensed and is related to applied pressure.
