Abstract

An apparatus for measuring pressure within a fluid path includes a housing defining the structure of the apparatus. The housing includes a fluid path that extends through the housing and allows a fluid to pass through the housing. The apparatus also includes a first volume chamber that is in fluid communication with the fluid path and has a first volume chamber opening, and a second volume chamber with a second volume chamber opening that is less than the first volume chamber opening. A diaphragm separates the first volume chamber from the second volume chamber and fluidly disconnects the second volume chamber from the fluid path. The diaphragm deforms based upon the pressure within the fluid path. The apparatus also includes an interface that is connectable to a pressure sensor, and the second volume chamber is in fluid communication with the interface.
