The present disclosure relates to a retractable assembly for immersion, flow and attachment measuring systems in analytical process technology that includes an essentially hollow cylindrically shaped housing having a service chamber formed in its interior, where the housing includes an encircling groove open to its interior, where the groove includes an expansion space expanding the groove, where the expansion space is arranged on the side of the groove facing away from the interior, and where the housing includes a leakage path, which connects the expansion space with the environment.

Retractable assembly

A tool and a retractable assembly for measuring at least one measured variable of a medium in a containment, comprising: an essentially cylindrical housing; an immersion tube, which is movable axially in the housing between a service position run out from the medium and a process position run into the medium; and an engagement apparatus secured on the housing; wherein a movable piston is provided in the engagement apparatus and at least a first position and a second position of the piston are provided. The engagement apparatus holds the immersion tube in the service position when the piston is located in the first position, especially when no energy supply is present, and the engagement apparatus holds the immersion tube in an intermediate position between the service position and the process position and prevents further movement of the immersion tube in the direction of the medium when the piston is located in the second position.

Retractable assembly for immersion-, flow- and attachment-measuring systems

A retractable assembly for immersion-, flow- or add-on measuring systems in analytical process technology for measuring at least one measured variable of a medium in a containment, comprising: an essentially cylindrical housing; an immersion tube, which is movable axially in the housing between a service position out of the medium and a process position in the medium; and a sensor for measuring the measured variable. The sensor is arranged in the immersion tube, wherein the sensor protrudes at least sectionally out of the immersion tube at the end of the immersion tube remote from the medium; and an openable and closable cover, which surrounds at least the section of the sensor protruding out of the immersion tube. The sensor in the opened state of the cover is mountable and demountable, respectively, in and from the immersion tube. The retractable assembly is characterized in that the cover at least sectionally travels with the movement of the immersion tube and in the process position is located at least sectionally in the housing.
