| 摘要 |
The invention relates to a heated tube system (10) having an inner tube part (11) conducting a fluid, the walls (112, 114) of which may be heated by an electrical heating conductor (14). In order to design the tube system (10) in a reliably operating fashion even for narrower radii and higher standards, according to the invention the outer part of the wall (112) is surrounded by a separately formed heating conductor (14) and the heating conductor (14) is surrounded by a separately formed outer layer (16), preferably made of a woven layer of a technical yarn such as glass fiber. The electrical current fed into the heating conductor (14) may preferably be regulated using a control device (24) to which a signal is sent from at least one of the temperature sensors (20; 22) integrated into the heated tube system (10). |
