Abstract
A yarn sensor (25) for monitoring at least one parameter of a traveling yarn (17), e.g., in spinning and bobbin-winding machines, has a measuring gap (16) 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 (21). At least a portion of the surface inside the measuring gap (16) is free of the coating (21). The metallic coating is connected with a heat conductor to remove heat via the metallic coating (21). Undesirable effects on the measurement results can be substantially reduced, and the quality of the measurement results can be increased.
Claims5
A yarn sensor for monitoring at least one parameter of a traveling yarn, the yarn sensor comprising a housing of non-conductive plastic material enclosing electronic components, an outer surface of the housing having a metallic covering for substantially enclosing the electronic components, the housing defining a measuring gap having an inside surface at least a portion of which is free of the metallic covering.
