One of the most promising directions in the development of systems for controlling of temperature of high-voltage power lines, fire alarm systems, oil and gas fields and others are DTS systems. Distributed Temperature Sensing systems is a rising technology which will be further actively developed in the near future. According to the forecasts, the price of such fiber-optic DTS systems will continue to decline while productivity of them will continue to increase. Distributed Temperature Sensing technology becomes more applicable and more popular for many applications in a wide range of industries.
DTS systems were actively involved in various areas of scientific and engineering developments since the 1980s as temperature systems which can measure temperature with a high degree of accuracy over significant distances. In addition to this, such optoelectronic systems were able to provide a continuous profile of the temperature distribution along the fiber-optic cable or other device. The main measuring principles were based on detecting the back-scattering of light using the Rayleigh, Raman and Brillouin principles.
The key to understanding of fiber-optic Distributed Temperature Sensing systems is awareness of the fact that the optical fiber itself is the sensor and the instrumentation provides measurements on every 1m along the length of the fiber. What does this mean? This means that the operator is able to receive temperature information at all points from the moment of cable installation. Real advantages of DTS systems become apparent when a temperature profile of the installation is required or when a large number of sensing points is crucial. DTS systems are much more convenient than any conventional temperature sensing technology.
Distributed Temperature Sensing technology becomes practical for many applications. For instance, one of the most promising technologies based on DTS principle is linear optical fire detection. Such fire detection allows to detect fire and localize the seat of the fire within a building with 1m resolution. Also DTS systems are applied, for instance, in the oil and gas industry. Systems in question are used to monitor the temperature log of the well. In addition to this, fiber-optic DTS systems provide an opportunity to upscale the measurements to large spatial extents and monitor the temporal dynamics of the hydrological processes. Recent enhancements of this technology based on distributed sensing system have allowed the balance of energy and fluid mass at watershed scale. However, it is difficult to say that about all cases of DTS application. These systems are involved in the power systems, in cables for better ampacity judgment and in safety applications like the mines are reviewed. So it is not surprising that the number of companies providing DTS systems is growing ever so much.
