Aircraft line system, has sensor wire with two electrical conductors, and insulator insulating one electrical conductor from other electrical conductor and comprising electrical resistor that is varied based on temperature

摘要

The system has a line area to be monitored, and an aircraft leakage monitoring element (2) with a sensor wire that is formed sectionwise in form of a coil with a set of windings. The sensor wire has two electrical conductors (12, 16), and an insulator insulating one electrical conductor (12) from the electrical conductor (16). The insulator has an electrical resistor that is varied based on temperature. The electrical conductor (16) surrounds the electrical conductor (12), and the insulator is arranged between the electrical conductors.
