Optical fiber distributed temperature monitoring system

Product introduction Jiangsu Electric Power Automation Co., Ltd. can have: DTS-MM optical fiber distributed temperature monitoring system, a new modular design, with good performance and system stability. The system is based on Raman principle and optical time-domain reflectometry (OTDR) principle. The system uses the entire temperature-sensitive optical cable as a temperature sensor. The system integrates computer, optical fiber communication, optical fiber sensing and photoelectric control technology In one, with the inherent safety, corrosion resistance, electromagnetic interference and other advantages of continuous online monitoring of a wide range of long-range temperature information for the electric power, coal, petroleum, transportation and other fields to provide high-quality temperature monitoring program. Features Structural features Modular structure, integrated with a powerful computer processing capabilities, with small size, simple structure, easy to carry and powerful advantages. Optical fiber sensing an optical fiber to achieve long-term temperature continuous online monitoring, with no electricity, intrinsically safe, free from electromagnetic interference, moisture and so on. Performance indicators The use of advanced semiconductor lasers, high sensitivity photodetector automatically adjusts the gain to overcome the optical device due to long working hours, resulting in the signal offset, the system long-term stability and reliability, the measurement range up to 10km, the accuracy can reach 1 ℃. Interface configuration Open communication structure, network port, serial port and other interfaces to achieve data input / output. Built-in 16 relay output node (scalable), with flexible remote control System software real-time display of temperature distribution curve; Quickly query the temperature curve of each point over time; With partition independent high temperature, low temperature, temperature difference, rapid warming alarm; web publishing capabilities.
