ABSTRACT:
A sensor assembly consists of a metallic pressure sensor cap welded to a tubular gland, which integrally forms a sealing edge on its one end opposing the pressure sensor cap side, a housing part, which has an opening formed therein such that the gland can penetrate the same, and a gland nut being turnably supported on a projecting portion of the gland for attaching the sealing edge to a process port. A stepped portion of the sensor cap is welded to a stepped portion of the gland, and the housing part is fixed to the outside surface of the gland in a position between the sensor cap and the sealing edge. Here, the sensor cap has an outer diameter, which is smaller than or equal to an outer diameter of the gland, so that the sensor cap being welded to the gland beforehand can be fitted into the opening of the housing part.
