  • Exhaust pressure transducer
    Patent number: 5844769
    Abstract: An exhaust pressure capacitive transducer includes an improved pressure sensing cavity configuration. The cavity is either in the form of a wide cylinder or a cone so that the housing structure does not underlie the deflecting portion of the diaphragm but only the nondeflecting peripheral edge portion thereof to eliminating any ledges underlying the diaphragm which could collect soot thereon and prevent the diaphragm from returning to its undeflected position and giving an improper pressure reading.
