A measurement plan designed to suit the intended use is necessary for measurement of the various physical parameters.
The interrogators operate on the basis of the Raman or Brillouin principles, for example. Raman devices need multi-mode fibers, while Brillouin devices need single-mode fibers.
Heatable fiber optic temperature measurement cables contain a copper wire in addition. These can be energised for short-term heating. Dynamic temperature measurement can be used to check a pipeline for leaks.
Fiber optic temperature measurement cables used for fire detection must undergo special fire testing (e.g. in accordance with IEC; see data sheets). These special cables must be designed to suit their intended use.
Key factors in the choice of cable are environmental parameters such as the location of the cable assembly or embedding, temperature range, mechanical load, water and dust, chemical substances, ionising radiation and hydrostatic pressure.
Typical applications are end-to-end temperature measurement, detection and location of overheating or overcooling, and identifying and locating leaks and fires.
