Armored Strain Sensing Cable is a kind of sensing optical cable which is base on professional BOTDR and BOTDA principle. The optical cable is composed of optical fiber as middle core, stranded steel wire and MDPE jacket.The fiber is in close contact with the stiffener and outer sheath, which can sense the external strain change in real time.The unique steel wires layer twisted structure design skillfully transforms the longitudinal tension of optical cable into transverse stress, and achieves the uniform stress distribution. Meanwhile, the fiber has strong mechanical performance, balancing the contradiction between the certain mechanical strength requirement and the fiber stress sensing to the greatest extent.The products are especially suitable for buried, embedded, embedded and other ways of wiring, application in building health monitoring, geological settlement, pipe deformation monitoring.
