ABSTRACT:
Pressure of a fluid within an enclosed duct is transmitted to a manifold tube by a U-shaped sensing probe, having openings in or adjacent each free end. The probe is attached at the mid-point between the legs to the manifold tube at a single opening in the latter and sealed in air tight engagement about the periphery of the manifold tube opening. Both ends of the probe communicate pressure to the interior of the manifold through a single opening at the mid-point of the U which is small with respect to the interior area of the manifold and with respect to the size of the manifold opening at which the probe is attached.
