N8511

Multi Channel Optical Fiber Strain Sensing System


The N8511 enables extensive high-accuracy monitoring for the early detection of cracks in concrete structures, mudslides and landslides on slopes along roads, and riverbank collapse by measuring Brillouin scattered light with an optical fiber sensor to measure strain.
