System Introduction

Distributed Temperature Measurement Fiber System (DTS) is a distributed temperature measurement product independently developed by our company based on the principles of fiber Raman scattering and Optical Time Domain Reflectometry (OTDR) positioning.
The system is a new temperature measurement system based on technologies such as fiber optic communication and spectral analysis, which has advantages such as small size, high sensitivity, high accuracy, strong anti-interference ability, and suitability for long-distance transmission.
Real time monitoring of the system can achieve early prediction of overheating (cold) faults or fires at measuring points, preventing them in advance. When the measuring point experiences overheating (cold) or fire, the fiber optic sensor can transmit real-time measurement data. The host temperature measurement software system will determine whether to alarm based on the alarm threshold. When the measured temperature reaches the set threshold, an alarm message will be issued, and the location of overheating or overcooling will be accurately determined based on the time of echo reception to guide maintenance work.
