嵌入式光学应变传感器

os3600,基于光纤布拉格光栅(FBG)侦探hnology and is available two gage lengths of 25 or 100 cm. Intended exclusively for embedding in concrete structures, disk ends of the os3600 form a solid bond to surrounding concrete or grout. Universal ends allow the user to employ bolt-on, weld-on, or custom end brackets for attachment to rebar or other structures before embedding.

粗糙的，铁氟龙和钢屏蔽主体，装甲电缆和可选的连接器保护配件使OS3600适用于恶劣环境。两个FBG在OS3600体内很好地保护。一个FBG测量应变，另一个FBG测量，提供集成温度补偿。由于没有将纤维保持在载体上的环氧树脂，因此通过设计确保了长期稳定性。

在具有振动线和箔应变计的并排比较，OS3600同样敏感和准确，同时提供100倍的疲劳寿命。OS3600应变计有资格用于恶劣环境，并提供基于FBG的传感器所固有的许多优点。

This sensor can be used alone or in series as a part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and less cumbersome than comparable electronic gage networks.
