Abstract

A system for rotationally securely plugging a sensor into a through-passage of a flow channel, the sensor including a sensor housing, the through-passage having an inner wall delimiting the through-passage and first and second inside diameters extending respectively along a first axis and a second axis, 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 essentially perpendicular to the first and second axis, the sensor housing having a longitudinal extension area along the third axis and being insertable into the through-passage. To ensure rotationally secure assembly of the sensor in its setpoint angular position, at least one protrusion is provided so that the sensor housing, in a plugged-in state, is rotatable in the through-passage by no more than 0.5° about the third axis.
