鎧裝大應變傳感光纜
Armored Large Strain Sensing Cable
產品描述
鎧裝大應變傳感光纜由傳感光纖、無縫鋼管、加強鋼絲和外護套組成。傳感光纖按一定的余長分布放在一根不銹鋼無縫管內，管內填充油膏。光纜受外界的應變時，光纖與油膏之間可以在一定的范圍內蠕動，感應微應力。通過精確地控制余長的分布，可以控制光纜探測應變的范圍。光纜具有很強的機械性能，適合室外的各種惡劣環境，滿足各種高強度安裝要求。
The armored strain sensing cable is composed of sensing fiber, seamless steel tube, reinforcing steel wire and outer sheath. The sensing fiber is placed in a stainless steel seamless tube with some excess length, and the tube is filled with jelly. The sensing fiber moves against the jelly by strain, which can monitor the change of strain. By precisely controlling the distribution of excess length of fiber, we can control detect range of cable.
產品特點Features
