Definitions
- the inflow and outflow openings 24 are arranged such that the measuring gas penetrates into the measuring gas space 23 perpendicular to the axis of the sensor element, while in the exemplary embodiment shown in FIG. 2, the measuring gas also penetrates into the measuring gas space 23 parallel to the axis of the sensor element 20.
- the ceramic fiber material 21 is arranged between the two walls of the double-walled protective tube 22 in such a way that the measuring gas only reaches the measuring gas space 23 after it has flowed through the ceramic fiber material 21.

Abstract
L'invention concerne une sonde électrochimique utilisée pour détecter la présence de constituants gazeux et/ou de concentrations gazeuses dans des mélanges gazeux, au moyen d'un élément de détection (20) entouré d'un tube protecteur (22). Ledit tube protecteur (22) permet à un gaz de mesure d'accéder à l'élément de détection (20). Un matériau fibreux céramique (21) placé à distance de l'élément de détection (20) dans le tube protecteur (22) se trouve dans ledit tube protecteur (22).
