Overview of frame fiber optic temperature measurement host
The distributed fiber optic temperature measurement system is a temperature analysis instrument based on fiber optics and laser monitoring technology. Capable of long-distance and large-scale distributed temperature monitoring. It can complete the temperature measurement and data storage of thousands of collection points on the optical fiber in one scan of the sensing fiber. A variety of alarm functions can detect potential accident hazards in the monitored objects in advance, locate and analyze them, especially the analysis of the temperature change process, and timely improve the level of safety production management. In addition, the distributed optical fiber temperature measurement system has inherent high stability and high reliability. Can provide long-term uninterrupted monitoring.
The distributed optical fiber temperature sensing system (D) detects temperature changes at different locations along the optical fiber based on the optical time domain reflection of the optical fiber and the temperature effect of the optical fiber back-R scattering to achieve truly distributed measurement. The working principle is mainly based on the difference in the light scattering rate caused by the different temperatures of the fiber body when the incident light passes through the optical fiber, which affects the change in the intensity of the scattered light received at the light emitting end, thereby calculating the temperature value there. . Since the propagation speed of light in the optical fiber is constant, the temperature distribution along the optical fiber body can be calculated based on the sequence and time interval of the scattered light received at the transmitting end.
