Abstract: Case 04-3942-U.S.                  APPLICATION OF                     ROBERT C. WHITEHEAD, JR.            DIFFERENTIAL PRESSURE TRANSMITTER WITH        PRESSURE SENSOR PROTECTION                      ABSTRACT OF THE DISCLOSURE      A differential pressure to electrical signal transmitter has a pair of barrier diaphragms and one or two central con-trol diaphragms located between the barrier diaphragms.  A chamber on the outside of one barrier diaphragm is pressurized with a first fluid, and a chamber on the outside of the other barrier diaphragm is pressurized with a second fluid.  First chambers between one of the barrier diaphragms and the control diaphragm, and a first length of capillary tubing connected between the first chambers and one chamber of a remotely located sensor capsule, are filled with a first incompressible fill liquid.  Second chambers between the other barrier diaphragm and the control diaphragm, and a second length of capillary tubing connected between the second chambers and another chamber of the sensor capsule, are filled with a second in-compressible fill liquid.  The pressures of the two fill liquids act on the opposite sides of a minute displacement sensing element, located between the two sensor chambers, to displace the element and cause it to produce an electrical output signal which is dependent upon the difference between the fill liquid pressures, and hence upon the difference between the pressures of the first and second fluids.  The control diaphragm is significantly stiffer than the barrier diaphragms, and causes an excess in either of the fluid pressures to bottom-out the corresponding barrier diaphragm, thereby preventing the excess pressure from reaching and damaging the sensing element.  The barrier diaphragms may be convoluted, or may be flat diaphragms which are pressurized to have a dome shape.  The capillary tubes minimize the transmission of sensor-damaging heat and/or pulses from the fluids to the sensing element by way of the fill liquids.
