鎧裝大應(yīng)變傳感光纜

Armored Large Strain Sensing Cable

產(chǎn)品描述

鎧裝大應(yīng)變傳感光纜由傳感光纖、無縫鋼管、加強(qiáng)鋼絲和外護(hù)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(nèi)，管內(nèi)填充油膏。光纜受外界的應(yīng)變時，光纖與油膏之間可以在一定的范圍內(nèi)蠕動，感應(yīng)微應(yīng)力。通過精確地控制余長的分布，可以控制光纜探測應(yīng)變的范圍。光纜具有很強(qiáng)的機(jī)械性能，適合室外的各種惡劣環(huán)境，滿足各種高強(qiáng)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(chǎn)品特點Features

◇ 光纖按預(yù)定的余長分布

Excess length of fiber can be controlled

◇ 管內(nèi)填充油膏，光纖受力時，光纖可以在一定的范圍內(nèi)蠕動

The fiber can sense the change when the cable is pull and the fiber will move against the jelly.

◇ 光纜具有很強(qiáng)的機(jī)械性能，適合各種惡劣環(huán)境，滿足各種高強(qiáng)度安裝布線

Cable is suitable for various kinds of environment with high mechanical performances.

用途

◇ 適合大應(yīng)變的光纖傳感使用

Embedded concrete or bury to test the sedimentation rate of building, bridge, tunnel, etc.
