铠装大应变传感光缆

Armored Large Strain Sensing Cable

产品描述

铠装大应变传感光缆由传感光纤、无缝钢管、加强钢丝和外护套组成。传感光纤按一定的余长分布放在一根不锈钢无缝管内，管内填充油膏。光缆受外界的应变时，光纤与油膏之间可以在一定的范围内蠕动，感应微应力。通过精确地控制余长的分布，可以控制光缆探测应变的范围。光缆具有很强的机械性能，适合室外的各种恶劣环境，满足各种高强度安装要求。

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.
