Tube-equipped, flanged, pressure transfer means, pressure measuring arrangement with such a tube-equipped, flanged, pressure transfer means and pressure measuring point with such a pressure measuring arrangement

A pressure measuring arrangement, comprising:

• a tube-equipped, flanged, pressure transfer structure, comprising:
• a flange for connecting the tube-equipped, flanged, pressure transfers structure to a tubular opening of a container or line, which tubular opening is surrounded by a counterflange;
• a tube, which is secured especially coaxially to said flange, and which protrudes from the plane of said flange, in order to protrude inwardly into said tubular opening;
• a hydraulic path, which extends from a first opening in a front end surface of said tube facing away from said flange through said tube and through the flange to a second opening in the rear end surface of said flange facing away from said tube;
• and an isolating diaphragm, which covers said first opening and is connected pressure-tightly with the front end surface of said tube along at least one peripheral edge, in order to form a pressure chamber between said isolating diaphragm and said front end surface of said tube, wherein:
• said pressure chamber and said hydraulic path are filled or fillable with a pressure transfer liquid, in order to transfer a pressure presiding at said isolating diaphragm to said second opening;
• said tube has at least a form-retaining front section with a first average diameter and a form-retaining intermediate section with a second average diameter, said first end surface is formed by an end face of said front section, said first average diameter is greater than said second average diameter, said intermediate section is arranged between said front section and said flange;
• and said front section has a first axial length, and said intermediate section has a second axial length, wherein said first axial length is less than said second axial length;
• and
• a pressure measurement transmitter with a pressure sensor, wherein:
• said pressure measurement transmitter is secured to the flange;
• and
• said pressure sensor is contactable with pressure presiding at said second opening.

Pressure measuring point, comprising:

• and said front section has a first axial length, and said intermediate section has a second axial length, wherein said first axial length is less than said second axial length;
• and a pressure measurement transmitter with a pressure sensor, wherein:
• said pressure measurement transmitter is secured to the flange;
• and said pressure sensor is contactable with pressure presiding at said second opening;
• a pressure measuring arrangement;
• and
• a line or a container having a tubular process opening and a counterflange around the process opening, wherein:
• said flange of the tube-equipped, flanged, pressure transfer structure is secured to said counterflange such that the tube-equipped, flanged, pressure transfer structure protrudes inwardly into said tubular opening.
