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.
