Abstract
A pressure measurement system includes a diaphragm and a chamber for exposing one side of the diaphragm to a fluid. A force transducer is provided for measuring force exerted by the fluid on the one side of the diaphragm independent of diaphragm position. A ferromagnetic plate is attached to the diaphragm to enable removable coupling of the diaphragm with a magnet permanently attached to the force transducer.
