Abstract:
1. A pressure sensor for measurement in hot, dynamic processes comprising: a cylindrical housing defining a front end that is configured to be disposed toward the locus of the hot, dynamic processes when the pressure sensor is taking measurements of the processes, the housing defining a back end disposed opposite the front end, the housing defining an annular shaped housing extension at the housing's front end; a round or annular membrane disposed in the housing behind the housing extension so as to be exposed to the hot process when the pressure sensor is taking measurements of the process, the membrane having at least an outer support wherein the outer support is mounted on the housing behind the housing extension; a measuring element disposed in the housing between the membrane and the rear end and wherein the measuring element is adapted to acquire measurement data due to an axial displacement of the membrane; and an annular heat shield which surrounds the housing extension and, except at the edges of the heat shield, defines a gap between the heat shield and the housing extension.
