Micro strain highly sensitive strain fiber

高敏感微应变传感光缆

High Sensitive Microstrain Sensing cable

产品描述

应力（应变）传感光缆是专业的基于BOTDA, ΦOTDR等干涉型原理为基础的应力及应变探测的传感光缆。光缆采用紧套结构，无任何余长，自带预应力，因此非常敏感。光缆易于施工，可采用直埋、表贴、嵌入等方式施工。可用于管道监测、建筑物建康监测、土方沉降监测等。

High sensitive microstrain sensing cable is a kind of stress and strain sensing optical fiber cable based on BOTDA principle. The cable adopts a tight sheath structure, without any residual length, with prestressing force, so it is very sensitive. The cable is easy to deploy, can be buried directly, surface paste, embedded and other ways of installing. It can be used for pipeline monitoring, building health monitoring, earth settlement monitoring, etc. 

产品特点

光缆的温度－应变，力应－应变具有非常好的线性关系，测量准确度和度度高；

The temperature - strain, force - strain of the cable has a very good linear relationship, and measurement accuracy and precision is very high;

光缆刚性强，弹性好，自然校直，非常利于布线；

Cable rigidity, good elasticity, natural alignment, very conducive to wiring;

光缆有预应力，无需预先张紧，敏感度非常高；

The cable has the prestress, does not need beforehand tensioning, the sensitivity is very high

光缆抗拉、抗挤压，保证施工过程不容易受安装材料干扰；

Cable has very good tensile strain resistance, anti-extrusion, which ensure that the cable is not easily affected by the installation materials when setting.

应用领域

隧道、桥梁、轨道、大坝、高速公路等，表面微小应变或位移的监测；

Monitoring of micro-strain or displacement on the surface of tunnels, Bridges, tracks, DAMS, highways, etc.;

敷设方式：

推荐采用表贴或刻槽嵌入方式布线。

It is recommended to use table stick or slot embedded wiring.
