Abstract
The pressure measurement system includes a diaphragm having a first and a second side and a chamber for exposing the diaphragm first side to a fluid. A force transducer is utilized for measuring force exerted by the fluid on the diaphragm first side. A plate and a captive portion of the diaphragm extending from the second side thereof and partially encasing a portion of the plate enables the plate to be secured to the force transducer with the use of a ferromagnetic plate and a magnet attached to the force transducer, the force transducer may be removably engaged with the plate.
