A differential pressure measuring probe with an improved signal to noise ratio is provided. The probe includes an slit surface with at least one longitudinally extending impact aperture communicating with a first plenum within the body of the probe. The width of the aperture is selected to be less than the width of the interior portion of a first plenum. A non-impact surface is provided with non-impact apertures to measure a second pressure such that differential pressure between the impact surface and the non-impact surface can be measured. |
