摘要： An example of a concentric probe includes an outer shroud having a bore that extends through the outer shroud, an inner shroud located within the outer shroud and having a bore that extends through the inner shroud, the inner shroud joined to the outer shroud via brazing, an annulus defined by a space between the inner shroud and a wall of the bore of the outer shroud, a plenum defined by a space between the inner shroud and the wall of the bore of the outer shroud, the plenum being in fluid communication with the annulus, and a transducer disposed within inner shroud.
