Abstract
An apparatus for monitoring the yarn delivered by an open end spinning turbine which has an electric motor for driving the turbine with a predetermined rpm. The apparatus includes a measured value transmitting arrangement responsive to changes in the current consumption of the electric motor for generating a signal when the change in the current consumption exceeds a predetermined threshold value. The measured value transmitting arrangement is responsive to a reduction in the current consumption of the electric motor and generates a yarn breakage indicating signal when the reduction in the current consumption falls below a predetermined value indicative of yarn breakage.
