Probe arrangement

摘要

A probe arrangement, in the case of which a probe is arranged within a tubular housing, wherein the tubular housing has at least one process window open to the process medium, and at least one functional element is secured on the probe and surrounded by the process medium. In order to suppress a taking along of the process medium during transfer of the functional element from the measured medium into a rinsing chamber, the tubular housing includes at least one treatment window open opposite the probe (3), preferably for washing, rinsing and/or calibrating the functional element, wherein the functional element is movable between the process window and the treatment window, and, during the measuring in the process medium, the at least one functional element is arranged approximately coincident with the at least one process window of the housing.

主权项

1. A probe arrangement, comprising:
a probe; and a tubular housing, with said probe being arranged within said tubular housing, wherein: said tubular housing has at least one process window open to a process medium; at least one functional element is arranged on said probe, which is surrounded by the process medium; said tubular housing has at least one treatment window lying opposite said probe, for washing, rinsing and/or calibrating said at least one functional element; said at least one functional element is movable between said at least one process window and said at least one treatment window, and, during measuring in the process medium, said at least one functional element is arranged approximately coincident with said at least one process window; said at least one functional element is arranged on said probe to extend laterally of said probe, and in the length direction of said tubular housing; said at least one treatment window is advantageously arranged opposite said at least one process window at an approximately an equal height; and said probe is mounted rotatably, whereby said at least one functional element is rotatable from a measuring position into a treatment position lying approximately coincident with said at least one treatment window and vice versa, from the treatment position back into the measuring position.
