Abstract :
The aim of this paper is to present an experimental procedure to measure yarn evenness in real-time using capacitive sensors; samples with several millimeters are analyzed, depending on the type of sensor used, to increase quality in production. The approach used allows a direct measurement in 1 mm range, allowing real-time actuation when faults or other parameters exceed the maximum acceptable value.
