  • Patent number: 11486770
    Abstract: A method for monitoring a line for a change in ambient conditions. The line includes a measurement line of a predetermined length which has a measuring conductor enclosed in an insulation with a known dielectric coefficient. An analog signal of defined frequency is generated and injected at a feed site. The signal is reflected at a predetermined reflection site and a resulting signal amplitude is measured at a defined measuring point. A measure for the ambient condition, particularly a temperature, is determined from the signal amplitude.

  • Patent number: 11041899
    Abstract: In a method for monitoring a line, a measuring signal is fed into a measuring conductor at a start time. The measuring signal is reflected at an interference point or at a line end and the reflected portion is monitored to check whether a threshold value is exceeded. If the threshold value is exceeded, a digital stop signal is generated and the transit time between the start time and the stop signal is analyzed.

  • Patent number: 11001157
    Abstract: A device has two machine parts that are movable relative to one another and are connected to each other by a supply line, along which a sensor line is mounted for measuring torsion of the supply line. The sensor line includes two conductors forming a conductor pair, which is stranded during production. The two conductors form a capacitor with a capacitance depending on the spacing between the two conductors. Depending on the direction of torsion of the supply line, the spacing between the two conductors is enlarged or reduced. The sensor line is connected to a measurement unit which is configured in such a way that a capacitance of the sensor line is measured, the torsion being ascertained using the capacitance.
