Abstract (en)
[origin: WO9728587A1] The invention concerns an encased tubular conductor (50) with the antenna (11) of a control and monitoring unit (15) mounted on its casing (5), facing towards the interior (4). The interior (4) acts as a wireless-transmission space for the transmission of information to a second antenna (51). This makes protected transmission possible over long distances. In addition, the exchange of information is also possible with sensors (7a to 7k) located in the interior (4) of the casing.
