摘要:
A pressure transducer assembly that uses static pressure compensation to capture low-level dynamic pressures in high temperature environments. In one embodiment, a method comprises receiving, at a first tube, a pressure, wherein the pressure includes a static pressure component and a dynamic pressure component; receiving, at a micro-filter, the pressure; filtering, by the micro-filter, at least a portion of the dynamic pressure component of the pressure; outputting, from the micro-filter, a filtered pressure; receiving, at a first surface of a first sensing element, the pressure; receiving, at a second surface of the first sensing element, the filtered pressure; measuring, by the first sensing element, a difference between the pressure and the filtered pressure, wherein the difference is associated with the dynamic pressure component of the pressure; and outputting, from the first sensing element, a first pressure signal associated with the dynamic pressure component of the pressure.
