Detection of large hollow pipe using proximity sensors

Bouncing effect in the pipe mill mechanically damages the proximity. Circulating trolley systems, cold strip lines, lifting bar conveyors, and other equipment are also used, in addition to roller conveyor systems.  Inductive proximity switches were used, which provided safe operation for large sensing distance, and even in the presence of water, dust, emulsions and oils.
