扁平型表贴应变传感光缆
Flat Type Strain Sensing Cable
产品描述 Description
扁平型表贴应变传感光缆是一种专业传感光缆,由紧包型应力传感光纤和松套型测温光纤组成，两种光纤分别排于护套两边，中间为带状结构，作为安装光缆的部件。整体光缆为扁平结构，可以采用钢钉直接安装或胶粘方式进行布线，特别适合用于隧道应变监测的环境，尤其是比较潮湿、无法使用胶粘表贴的方式的环境。
The flat type strain sensor cable is a kind of professional sensing cable, which is composed of the compact type stress sensor fiber and the loose type temperature measuring fiber. The two kinds of fiber are arranged on both sides of the sheath respectively, and the middle is a ribbon structure, which is used as the component to install the cable. The whole cable is flat, which can use steel nail direct installation or adhesive way for wiring, especially suitable for tunnel strain monitoring environment, especially for more humid environment, where can not use adhesive table paste way to install.
产品特点
1，温度和应变光纤集成在一起，可以同时进行温度和应力监测
Temperature and strain sensor fiber are integrated together for both temperature and stress monitoring；
2. 扁平结构，适合钉装固定或胶粘方式固定，安装方便；
Flat structure, which is easy to install by fixing by nailing or gluing
推荐应用 Application
高速公路隧道、地铁隧道等的温度和应变监测
Strain and temperature monitoring for tunnel of express way, metro, etc
