A pressure transducer has an H-shaped cross-sectional header having a front and a back section. The front and back sections are of equal diameter and are circular. Each front and back section has a depression with an isolation diaphragm covering the depression. Each diaphragm is of equal size and the depressions communicate one with the other via a central channel in the central arm of the H. A pressure sensor communicates with the channel, where the pressure sensor responds to a first pressure applied to the first isolation diaphragm and a second pressure applied to the second isolation diaphragm. The pressure sensor produces an output equal to the difference in pressure. The differential pressure transducer having both diaphragms of the same size and still enabling leads from the sensor to be brought out.
