Optical Displacement Sensor Node

The Optical Displacement Sensor Node is an instrument which uses optical means to take high precision displacement measurements and pass these through Senceive’s wireless communications network to a Gateway.

Optical Displacement Sensor Node

About

It can also be combined with Senceive’s world-leading triaxial tilt sensor to obtain high precision tilt measurements that are linked to an external reference.

Optical Displacement sensing is perfect for many 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.
