BOTDA铠装感温光缆
BOTDA Armored Temperature Sensor Cable
产品描述
BOTDA铠装感温光缆是一种基于布里渊散射原理光纤传感系统的温度补偿光缆。光缆由PBT松套管或无缝钢管、铠装编织层、芳纶加强层以及LSZH外护套组成。光纤在松套管里有一定的余长，在光缆正常的应力范围内不会产生应变反应。产品可以用于布里渊系统的温度补偿光缆或基于布里渊系统的测温光缆。
BOTDA armored temperature sensing cable is a temperature compensation cable based on Brillouin scattering principle. The cable is composed of PBT loose tube or seamless steel tube, armored braid layer, aramid yarn reinforcement layer and LSZH outer sheath. The fiber has a certain excess length in the loose tube, which will not strain response within the normal stress range of the cable. The product can be used for brillouin system temperature compensation cable or DTS sensor cable.
产品特点
松套管结构，精确控制余长 Loose tube structure, excess length is controlled.
拉力范围内应力不敏感 Strain is not sensitive in the normal range of tensile strains.
该光缆防鼠,防蚁 Anti mouse bite, anti ants bite.
