ABSTRACT:
Pressure transducers are used to measure pressure under high temperature, hostile environments, including in gas turbine combustors and internal combustion engines. The present a pressure transducer comprises a member having a first end and a second end, a diaphragm sealed within the member at the first end, a sensor sealed within the member at the first end and in operable communication with the diaphragm, a first plate having a plurality of apertures, the first plate being attached to the member at the second end, a second plate having a plurality of apertures, the second plate being attached to the tubular member at the second end and being spaced from the first plate, and wherein the apertures of the first plate are not aligned with the apertures of the second plate.
