"Fiber detection for use in a system for detecting temperature distribuu00ecda, temperature detection system and detection method distribuu00ecda temperature distribuu00ecda".This is a fiber of detection for use in a system for detecting temperature distributed,It comprises an optical fiber to be installed in a measuring region in which should be carried out a temperature measurement, which incorporates a reflector element.As a union between portions of the fiber, and a portion of the fiber wrapped which has substantially no contribution to the spatial extent of the optical fiber when installed.In use, the effect of any light propagating forward incident on the reflector element that is returned to the detection by the system, and saturates the detector.It can be eliminated by removal of part of the signal is detected which corresponds to the coiled portion, after which the detector will be recovered.The remaining parts of the signal can be used for the derivation of the temperature profile distributed since these parts represent the total length of fiber detection due to the absence of ext.Ensu00e3o space of the winding. May be provided with windings on both sides of the reflector element for temperature detection techniques of double end.
