A temperature measurement is performed using a sensor cable. The measuring arrangement has a first signal conductor, a feed unit for feeding a measurement signal into the signal conductor, and an analyzing unit which ascertains and analyzes a change in the signal transit time of the measurement signal as a result of a temperature-induced change in a first temperature-dependent dielectric constant and is configured to derive a temperature signal from the ascertained signal transit time. The first signal conductor together with a second signal conductor forms the sensor cable, and each of the two signal conductors is surrounded by an insulation which is made of a first material that has a first dielectric constant in the first signal conductor and which is made of a second material that is different from the first material and has a second dielectric constant in the case of the second signal conductor.
