Distributed fiber optics for temperature sensing in buildings and other structures

An optimized facility management and the risk assessment of buildings need a permanent up-dating of relevant data. Temperature is a key parameter to design and control air-conditioning installations; time and space variations of the temperature indicate damage situations in an early stage so that measures can be taken for damage prevention, for warning and for controlling escape routes in buildings. The fiber optic temperature sensing technique opens new possibilities and chances for permanent surveying of buildings, power supply installations, communication and data transmission systems.
