Embeddable Optical Strain Sensor

基于光纤布拉格光栅（FBG）技术的OS3600，可用于25或100厘米的两个量长。专门用于在混凝土结构中嵌入，OS3600的盘端形成固体键与周围的混凝土或灌浆。通用结束允许用户使用螺栓接通，焊接或定制端支架，以便在嵌入之前附加到钢筋或其他结构。

A rugged, Teflon and steel-shielded body, armored cables, and optional connector protection fittings make the os3600 suitable for harsh environments. Two FBGs are well protected inside the os3600 body. One FBG measures strain, and the other provides for integrated temperature compensation. Since there are no epoxies holding the fiber to the carrier, long-term stability is ensured by design.

In side-by-side comparisons with vibrating wire and foil strain gages, the os3600 is equally sensitive and accurate, while providing 100 times more fatigue life. The os3600 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.

该传感器可以单独使用或串联使用FBG传感器阵列的一部分。对于这种阵列的安装和布线比可比较的电子计量网络的昂贵且繁琐较少。
