分布式测温系统 Distributed Temperature Sensing (DTS)

产品介绍 Product Introduction

分布式测温系统（DTS）是一种先进的光纤温度监测技术，可沿整条光纤光缆进行连续、实时的温度测量。系统采用光时域反射（OTDR）技术结合拉曼或布里渊散射原理，能够高精度地探测光纤每一点的温度变化。无需安装大量独立的点式传感器，即可对电力电缆、油气管道、工业过程、火灾监测等大型资产进行全面的热监测。 Distributed Temperature Sensing (DTS) is an advanced fiber optic temperature monitoring technology that provides continuous, real-time temperature measurements along the entire length of an optical fiber cable. Using optical time-domain reflectometry (OTDR) combined with Raman or Brillouin scattering principles, DTS systems can detect temperature variations at every point along the fiber with high precision. This enables comprehensive thermal monitoring across large assets such as power cables, oil and gas pipelines, industrial processes, and fire detection systems without the need for individual point sensors.
