Abstract
The invention is directed to the measurement of pressure and pressure differentials utilizing ferromagnetic fluids. The inventive devices include a ferromagnetic fluid physically arranged to be subjected to the pressure being monitored. Changes in the monitored pressure cause physical displacement of the ferromagnetic fluid. The displacements are detected by utilizing the magnetic characteristics of the ferromagnetic fluids to generate useful output signals.
