The fiber optic distributed temperature monitoringsystem (DTS) is a relatively complete and ideal high-tech equipment that integrates advanced fiber optic and laser technologies in the world, and uses fiber optic as a sensing detector for temperature monitoring. The DTS system is currently one of the most advanced and effective online systems in the world
Distributed temperature monitoring system. Nowadays, it has been widely used in many fields such as electricity, petroleum, chemical industry, water conservancy, and transportation.
Characteristics of multi-channel distributed temperature sensing fiber optic system
(1) The multi-channel distributed temperature sensing fiber optic system can set temperature alarm points according to customer requirements and has recoverability. The DTS system can output temperature values and alarm signals in the form of analog signals without affecting the long-term operation of the system, provided that the fiber optic detector is not damaged. When the temperature exceeds the predetermined range and falls back, it has the characteristic of being reusable.
(2) The multi-channel distributed temperature sensing fiber optic system can strictly follow the predetermined temperature point alarm, with fast response speed and almost no error. Different temperature warning lines can be set at the same monitoring point or monitoring area to achieve low temperature alarm, early warning, fire alarm, etc., and realize intelligent early warning control function. At the same time The DTS system can also monitor and alarm based on the temperature rise rate.
(3) The multi-channel distributed temperature sensing fiber optic system can clearly display the temperature changes at each point within the longest 30km line on the terminal (the shortest measurement point can be set to 0.25m), providing accurate temperature value output and spatial positioning.
(4) The fiber optic detector of the multi-channel distributed temperature sensing fiber optic system adopts the transmission of optical signals, which has no electrical characteristics and is inherently safe. It can be applied in strictly explosion-proof areas and environments with high voltage and strong magnetic fields or severe electromagnetic pollution, without any electromagnetic interference to the system due to conduction. Through different outer sheath materials, DTS monitoring system can adapt to various environments. For example, the alloy outer sheath optical fiber is selected to resist mechanical impact and aging, and can withstand high temperatures up to 500C.
(5) The multi-channel distributed temperature sensing fiber optic system can perform self inspection of the safety and effectiveness of the host and the fiber optic cable itself at any time. Any system functional damage caused by connection fusion or external damage will be detected by the host, and the accident point will be accurately located to determine the cause of the accident. External equipment can be easily used to repair the system without affecting its normal operation.
