ABSTRACT:
A pressure transducer apparatus including: first and second pluralities of piezoresistors each coupled in Wheatstone bridge configurations, wherein the bridges are coupled together to provide a first output being indicative of a differential pressure; and, a third plurality of piezoresistors coupled in a Wheatstone bridge configuration and being suitable for providing a second output being indicative of an absolute line pressure. A compensator may be employed for adjusting the first output for line pressure variation responsively to the second output.
