ABSTRACT:
A pressure transducer employs a tubular glass structure of a "D" shaped cross section, with the arcuate section of the "D" shaped configuration being substantially thicker than the base section. A sensor array is positioned on the underside of the base section while a pressure conducting fluid is directed through the tubular member to provide deflection of the base to cause the sensor array to provide an output indicative of pressure variations in the fluid medium. The sensor array as positioned on the underside of the base is both electrically and mechanically isolated from the pressure conducting medium.
