Probe for measuring a property of a gas from an internal combustion engine , notably a motor vehicle engine , the probe comprising: - a sensitive element , - an internal cage capping the sensitive element , the internal cage comprising first orifices , notably distributed over a first circumference of the internal cage , the internal cage delimiting an interior environment (I) within the internal cage , - a cap capping the internal cage , the cap comprising second orifices , notably distributed over a second circumference of the cap , the cap delimiting an exterior environment (E) on the outside of the cap , characterized in that the internal cage and the cap are arranged relative to one another in such a way as to be able to be configured: - in a first position (P1) in which a first cross-sectional area (A1) for the passage for gas between the exterior environment (E) and the interior environment (I) is created, the first area (A1) being the sum of the areas of the intersections of the projections of the first orifices of the internal cage and of the second orifices of the cap onto the internal surface of the internal cage , the projection being done orthogonal to the internal surface of the internal cage , or - in a second position (P2) in which a second cross-sectional area (A2) for the passage of gas between the exterior environment (E) and the interior environment (I) is created, the second area (A2) being the sum of the areas of the intersections of the projections of the first orifices of the internal cage and of the second orifices of the cap onto the internal surface of the internal cage , the projection being done orthogonal to the internal surface of the internal cage , the second area (A2) being greater than the first area (A1). - a sensitive element , - an internal cage capping the sensitive element , the internal cage comprising first orifices , notably distributed over a first circumference of the internal cage , the internal cage delimiting an interior environment (I) within the internal cage , - a cap capping the internal cage , the cap comprising second orifices , notably distributed over a second circumference of the cap , the cap delimiting an exterior environment (E) on the outside of the cap , characterized in that the internal cage and the cap are arranged relative to one another in such a way as to be able to be configured: - in a first position (P1) in which a first cross-sectional area (A1) for the passage for gas between the exterior environment (E) and the interior environment (I) is created, the first area (A1) being the sum of the areas of the intersections of the projections of the first orifices of the internal cage and of the second orifices of the cap onto the internal surface of the internal cage , the projection being done orthogonal to the internal surface of the internal cage , or - in a second position (P2) in which a second cross-sectional area (A2) for the passage of gas between the exterior environment (E) and the interior environment (I) is created, the second area (A2) being the sum of the areas of the intersections of the projections of the first orifices of the internal cage and of the second orifices of the cap onto the internal surface of the internal cage , the projection being done orthogonal to the internal surface of the internal cage , the second area (A2) being greater than the first area (A1). <EOS>
