Claim Text:
1. A sensor system for rotationally securely plugging a sensor into a through-passage of a flow channel, comprising: a sensor arrangement including a sensor housing, the through-passage having an inner wall delimiting the through-passage, the through-passage having a first inside diameter extending along a first axis and a second inside diameter extending along a second axis which is perpendicular to the first axis, the first inside diameter being greater than the second inside diameter, a plug-in direction of the sensor housing into the through-passage defining a third axis which is essentially perpendicular to the first axis and the second axis, the sensor housing having a longitudinal extension area along the third axis, the longitudinal extension area having an outer wall, the longitudinal extension area being insertable into the through-passage; wherein at least one protrusion is provided so that the sensor housing, in a plugged-in state, which is when the longitudinal extension area is inside the through-passage, is rotatable in the through-passage by no more than 0.5° about the third axis, the at least one protrusion (a) being provided on the inner wall of the through-passage and projecting inwardly from the inner wall of the through-passage into the through-passage or (b) being provided on the outer wall of the longitudinal extension area of the sensor housing so that, in the plugged-in state, the at least one protrusion projects inside the through-passage, outwardly away from the outer wall of the longitudinal extension area, and towards the inner wall of the through-passage.
