Abstract
A protective tube for an apparatus for determining and/or monitoring a process variable of a medium in a containment includes a tubular element for receiving a measuring insert of the apparatus, wherein the tubular element is securable to the containment such that the tubular element extends inwardly into an internal volume of the containment, wherein the tubular element includes an inlet opening and an outlet opening arranged on mutually oppositely lying sides of the tubular element. The present disclosure relates, furthermore, to an arrangement for determining and/or monitoring a process variable of a medium in a containment, the arrangement including an apparatus for determining and/or monitoring the process variable with a measuring insert and a protective tube according to the present disclosure.
Claims12
An arrangement for determining and/or monitoring a process variable of a medium in a containment, the arrangement comprising:
- an apparatus configured to determine and/or monitor the process variable in the containment, the apparatus comprising:
- a measuring insert, which serves for determining and/or monitoring the process variable;
- and
- a protective tube comprising a tubular element configured to receive the measuring insert, wherein the tubular element is securable to the containment such that the tubular element extends, at least partially, inwardly into an internal volume of the containment,
- wherein the tubular element includes an inlet opening and an outlet opening, wherein the inlet opening and the outlet opening are arranged on mutually oppositely lying sides of the tubular element, and wherein the inlet opening and/or the outlet opening is/are arranged in a region of a lateral surface of the tubular element, and
- wherein the protective tube is introducible into the containment such that an installed angle between a longitudinal axis of the protective tube and an imaginary, horizontal line lies in the range between 0° and −90°.
An arrangement for determining and/or monitoring a process variable of a medium in a containment, the arrangement comprising:
- an apparatus configured to determine and/or monitor the process variable in the containment, the apparatus comprising:
- a measuring insert, which serves for determining and/or monitoring the process variable;
- and
- a protective tube comprising a tubular element configured to receive the measuring insert, wherein the tubular element is securable to the containment such that the tubular element extends, at least partially, inwardly into an internal volume of the containment,
- wherein the tubular element includes an inlet opening and an outlet opening, wherein the inlet opening is arranged in a region of a lateral surface of the tubular element, wherein the outlet opening is arranged in an open distal end face of the tubular element, which end face faces the medium when the tubular element is secured to the containment, and
- wherein the protective tube is introducible into the containment such that an installed angle between a longitudinal axis of the protective tube and an imaginary, horizontal line lies in the range between 0° and −90°.
