In a sensing and analysing system for a yarn feeder with yarn storing unit (2), one or more sensor elements (8a, 8b, 8c) which may be coupled to one or more circuits (10, 11) are used for evaluating or sensing sensor information. At least one sensor element is placed in the unit (2'), from a yarn detection standpoint, in an uncritical relationship to the unit's yarn transporting surface (2a) and a yarn turn (6) travelling forward on this. The transmitting members (16, 18) are designed to relay information from each sensor element in the unit in unprocessed or processed form to receiving members (29) located outside the unit. Energy emitting members within the unit ensure energy supply to the sensor elements and the circuits belonging thereto. When using optical emitting elements, these are included in an arrangement which supplements or alternatively substantially reduces the influence of vibrations in the unit on the sensing or analysing result. |
