A TRANSDUCER FOR MEASURING THE PRESSURE OF A FLUID HAS A HOUSING (100) HAVING A FLUID CONTACT REGION (102), A CAVITY DIVIDED FROM THE FLUID CONTACT REGION BY A DIVIDING WALL (200), AND AN APERTURE (202) THROUGH THE DIVIDING WALL. A SENSOR COMPONENT (110) IS LOCATED IN THE CAVITY AND HAS A SUBSTRATE CARRYING A PRESSURE SENSOR. A RIGID SUPPORT BLOCK (114) IS MOUNTED ON THE SUBSTRATE (112) AND INCLUDES A SURFACE FACING THE DIVIDING WALL OFF THE HOUSING. A SPIGOT (116) FROM THIS SURFACE EXTENDS INTO THE APERTURE (202) OF THE DIVIDING WALL. A PASSAGE EXTENDS THROUGH THE SPIGOT (116) AND THE SUPPORT BLOCK TO THE SENSOR ON THE SUBSTRATE. THE PASSAGE IS FILLED WITH A PRESSURE TRANSMITTING MEDIUM. A RESILIENT SEAL (108) IS LOCATED AROUND THE SPIGOT (116) AND SANDWICHED BETWEEN THE SUPPORT BLOCK SURFACE AND THE DIVIDING WALL (200) OF THE HOUSING (100). A RECEIVER (122) IS SECURED INTO THE HOUSING (100). THE RECEIVER HOLDS THE SEAL, WITH THE SPIGOT (116) IN THE APERTURE (202). |
