MuST FBG Deformation Sensor
Long-gauge 可变形传感器坚固且易于安装
描述
MuST FBG 变形传感器是将静态或动态距离变化转换为预应力光纤布拉格光栅反射波长变化的传感器，可通过SMARTEC读数单元进行测量.
传感器由有源和无源部分组成。活动部分包含测量光纤并测量其两端之间的变形，将其转化为光纤布拉格光栅的波长偏移。无源部分对变形不敏感，用于将传感器连接到读取单元。在传感器的无源部分，可以安装一个松散的光纤布拉格光栅用于温度检测和补偿.
这些传感器采用单端，双端和链接配置。使用我们的读数单元，可以在同一通道上连接多达7个全量程温度补偿传感器（或者最多4个温度补偿+ 4个）。传感器采用E2000-APC连接器或用户规格终止.
传感器可以快速方便地安装，而不会影响施工进度。它们可以直接嵌入混凝土和砂浆或表面安装.
