Abstract
A turbidity sensor for a water-bearing domestic appliance includes a sensor housing having a housing main part and two housing projections protruding from the housing main part side by side and at a distance from one another, where the two housing projections delimit between them a measuring channel for a liquid to be measured. One of the housing projections emits a measuring light beam along a measuring path which runs transversely through the measuring channel to the other housing projection. The measuring path crosses the measuring channel in the channel longitudinal direction remote from a point of smallest channel width of the measuring channel or the measuring channel has a constriction at a longitudinal distance from its longitudinal midpoint, at which constriction the channel width is smaller than in a region of a longitudinal midpoint.
