Distribution Cable Optical Fiber Temperature Measurement Device

Model: DX-DLS100-CWG1

I. Product Overview

The distribution cable optical fiber temperature measurement device mainly consists of a distributed optical fiber temperature measurement host and a multimode temperature-sensing optical cable. The optical fiber serves both as a sensor and a transmission medium. The system transmits optical pulses along the fiber and utilizes the temperature-dependent scattering effects within the fiber to monitor the temperature of the cable-laying area in real-time online. It can detect minute temperature changes, providing accurate and continuous temperature data, enabling large-scale, long-distance, real-time, rapid multi-point measurement of spatial temperature distribution.

II. Main Functions

1.Utilizes distributed optical fiber temperature measurement technology, based on the optical time-domain reflection principle and Raman scattering effect of optical fibers, to determine the temperature distribution along the fiber by detecting the information of reflected light in the fiber;

2.Measurement distance can reach several kilometers, the number of channels can be customized, with wide coverage, accurately locating fault positions with a positioning accuracy of <1m;

3.Features high-temperature early warning function, flexible alarm methods, enabling differential and fixed temperature multi-level alarms to ensure reliable alarm in the early stages of fire;

4.Equipped with 1-16 temperature measurement channels, conventional fiber temperature measurement range -40°C to 85°C, special fiber temperature measurement range -40°C to 300°C.

III. Technical Parameters
