ABSTRACT:
A pitot pressure sensing probe assembly is made up of individual components comprising a barrel formed with a longitudinal interior passageway and a conical end cap at its leading end. A strut that has stamped or formed sections secured together to form the strut with a compound curvature includes a neck that has a bore to receive a hub of the barrel. The end cap has a pitot port for sensing fluid pressure. The barrel includes a water trap at its leading end for trapping water and permitting it to drain through a hole in the conical end cap. The longitudinal internal passageyway carries the fluid pressure sensed by the pitot port to remote instruments. The individual components are easily formed and are secured together to make the pitot pressure sensing probe assembly.
