Quality of the ropes and cables requires exact recording and control of the motion sequences. In the past, slip rings have been applied for signal transmission, with corresponding susceptibility to trouble in continuous operation. The particular challenge when changing to industrial radio technology was, and still is today, the very crowded and also metallic environment of the radio link, and the high speed with which coil carrier and rotor move against each other.
“In view of the particular requirements, we have regarded the conversion from slip ring to radio technology rather skeptically in the beginning. However, the prospect of higher operational safety finally has let us take this step and we have not been disappointed“, was the feedback of the responsible expert Ralph Püschel of the technical maintenance department on the project.
