摘要：A differential-pressure transducer whose main body is formed with opposingend faces and a passage extending between these end faces, the passage being filledwith a non-compressible liquid. Mounted adjacent each end face is a pressure-sensingdiaphragm, the two diaphragms being interconnected by a rod extending through thepassage and terminating at each end in a disc. The diaphrams are secured to theperipheries of the discs, the rod being axially displaced in accordance with a differentialpressure applied to the diaphragms. Disposed adjacent the end faces of the discs or theend faces of the main body is at least one temperature-compensating diaphragm whichserves to absorb the expansion and contraction of the liquid in the passage caused bychanges in ambient temperature.
