Abstract

The invention relates to a measuring device consisting of at least one water sensor mounted on an optical fiber cable for detecting the inlet of water. The water sensor has a water-reactive swelling body and an optical fiber segment that can be bent by said body. The humidity rise caused by the bending of said segment can be measured by a measuring instrument mounted at the beginning or the end of the cable.
