Optical Displacement Sensor Node

Optical Displacement Sensor Node

The Optical Displacement Sensor Node is an instrument which uses optical means to take high precision displacement measurements. These outputs are then passed through Senceive’s wireless communications network to a Gateway.

    The distance measurement provides information about the deformation of a targeted structure and the tilt measurement informs the user on the stability of the sensor itself and of the reference structure where it is mounted.

    Optical Displacement sensing is ideal for many structural and geotechnical monitoring applications, including those measuring:

    • Convergence/divergence for tunnel/arch intrados or bridge abutments
    • Vertical movements for structural settlement/heave
    • Lateral movements such as rail track slew
    • Earthworks and embankment movement
    • Water level monitoring/dewatering
