Abstract
A yarn sensor () for monitoring at least one parameter of a traveling yarn (), e.g., in spinning and bobbin-winding machines, has a measuring gap () and a housing made of a non-conductive plastic material for containing electronic components. The housing surface is covered by a metallic coating such that the electronic components are surrounded by the coating (). At least a portion of the surface inside the measuring gap () is free of the coating (). The metallic coating is connected with a heat conductor to remove heat via the metallic coating (). Undesirable effects on the measurement results can be substantially reduced, and the quality of the measurement results can be increased.
