产品描述Description
定点式应变传感光缆是一种专业BOTDR和BOTDA原理研究的一种应力、应变传感光缆，光缆由中心的紧包型应变传感光纤+铠装保护层+热塑性外护套组成。光纤与铠装层处于自由活动状态,再通过一定间距对应力传感光纤与铠装层和外护套进行固定,从而实现空间非连续非均匀的分段,应变测量结果可直接进行位移量的计算
Fixed-point strain sensing optical cable is a kind of stress and strain sensing optical cable which designed for BOTDR and BOTDA sensing system. The optical cable is composed of the compact strain sensing optical fiber in the center, armored protective layer and thermoplastic outer sheath. T The optical fibers are interactively fixed in the armored tube by a certain distance, which device the cable to several distances to monitor.
产品特点Features：
通过间隔地固定光纤以实现光缆的分区测量；To divide the cable to several detective distance through the interval fixed partition of fiber
分区点可见，便于固定安装；The fixed point is easy to install.
应变光纤可以选用不同类型的光纤；The strain sensing fiber can be chosen
应变光纤被铠装钢管保护，可适合各种恶劣环境The fiber is protected by the armored tube, which make the cable suitable for various application environment.
推荐用途Recommend applicatons
边坡沉降监测 slope settlement monitoring
