扁平型表貼應變傳感光纜
Flat Type Strain Sensing Cable
產品描述 Description
扁平型表貼應變傳感光纜是一種專業傳感光纜,由緊包型應力傳感光纖和松套型測溫光纖組成，兩種光纖分別排于護套兩邊，中間為帶狀結構，作為安裝光纜的部件。整體光纜為扁平結構，可以采用鋼釘直接安裝或膠粘方式進行布線，特別適合用于隧道應變監測的環境，尤其是比較潮濕、無法使用膠粘表貼的方式的環境。
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.
產品特點
1，溫度和應變光纖集成在一起，可以同時進行溫度和應力監測
Temperature and strain sensor fiber are integrated together for both temperature and stress monitoring；
2. 扁平結構，適合釘裝固定或膠粘方式固定，安裝方便；
Flat structure, which is easy to install by fixing by nailing or gluing
推薦應用 Application
高速公路隧道、地鐵隧道等的溫度和應變監測
Strain and temperature monitoring for tunnel of express way, metro, etc
