Abstract
A differential pressure transducer comprising: a housing having a first end containing a first recess, and an oppositely disposed second end containing a second recess; first and second isolation diaphragms respectively enclosing said first and second recesses and forming in conjunction therewith first and second cavities; first and second headers secured within said housing and being electronically coupled together; and, a pressure sensor being adapted to withstand an excess in either said first or second pressures and secured to said first header so as to isolate said first and second cavities from one another and being responsive to a first pressure applied to said first diaphragm and a second pressure applied to said second diaphragm to produce at least one signal indicative of a difference between said first and second pressures.
