Abstract
A protective tube, in particular for sealed introduction into a process space having a flow directed in a direction, having a hollow body, which is closed at its lower end, an opening at its upper end for introducing a temperature sensor; and at its upper end has a contour for sealing to a process space. The hollow body is cylindrical inwardly, an outer contour of the hollow body tapers toward the closed lower end, and at least in sections, at least one helix structure is arranged on the outer contour and/or at least in sections, at least one helix structure is arranged in the outer contour. A gas sample collector for introduction into a process space is also provided.
