Abstract
A sensing probe having a hollow tube for disposition in a flow stream is provided with an internal stiffening rod. A volume between the stiffening rod and the inner surface of the tube communicates with an open end of the sensing probe. In one embodiment, oppositely directed spiral grooves are formed in the surface of the stiffening rod to define the volume. A method of manufacturing the sensing probe includes first inserting a stiffening rod into a tube and then turning the tube to a desired wall thickness.
