Product Details
Data Centers Infrastructure
Strain sensing cable can support data center campuses and critical digital infrastructure where site movement or structural stress could affect long-term reliability.
Energy and Pipelines
Support strain monitoring along pipelines, terminals, compressor stations, substations, and remote generation infrastructure.
Transportation and Civil Infrastructure
Monitor bridges, tunnels, rail corridors, embankments, retaining structures, roads, and underground infrastructure.
Defense and Critical Facilities
Support movement monitoring across hardened structures, underground utilities, secured facilities, and remote infrastructure.
Industrial, Mining, and Ports
Monitor structural movement, foundation settlement, process-area infrastructure, and high-risk physical assets.
Water, Environmental, and Land Management
Support monitoring of dams, levees, canals, slopes, soil movement, and other large-scale civil assets.
Features & Benefits
Integrity
- Designed for Brillouin Distributed Strain Sensing applications and strain measurement up to 1% elongation.
- Singlemode sensing fibers and interlocking strain-transfer layers help couple physical movement from the monitored asset into the fiber.
- Compact, structured, and steel-armored variants use Fiber-in-Metal-Tube construction with hermetically sealed stainless-steel tube protection.
Protection
- Four construction options allow the sensing cable to be matched to the environment and physical demands of the installation.
- Non-metallic cable provides a lightweight all-dielectric design with EPR outer sheath protection.
- Compact and structured designs combine PA outer sheaths with protected metal-tube sensing cores.
Access
- Compact cable constructions support routing through constrained pathways, structures, and buried routes.
- All cable variants support a minimum bend radius of 20x cable diameter under tensile load and 15x cable diameter without tensile load.
- Available accessories include loops, fan-outs, connectors, mounting brackets, anchors, and splicing kits for strain sensing cable.
Investment
- Four cable constructions allow customers to select the appropriate balance of strain sensitivity, environmental protection, mechanical durability, and installation weight.
- Structured and steel-armored designs support applications requiring optimized strain transfer and increased protection in harsh, buried, or subsea environments.
- All product families are tested in accordance with IEC 60794-1-2.
