OPTICAL DISPLACEMENT SENSOR NODE
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.
Description
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. 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 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
Features
- Fully integrated unit
- Extremely low noise performance
- Optical sensor resolution of 0.1 mm and repeatability of ± 0.15 mm
- Triaxial tilt sensor resolution of 0.0001° (0.0018mm/m) and repeatability of ±0.0005° (±0.009 mm/m)
- Integrated long life battery
- 10 years battery life, including when acting as a relay node within the mesh communications network
- Easy to align with target when using the magnet triggered aiming mode
- Integrated temperature sensor
- Versatile mounting options
- Waterproof to IP66/IP67/IP68
- Firmware is remotely upgradeable over the air via the gateway reducing costly site visits (FlatMesh)

TILT BEAM MEMS
In stock
MEMS Tilt Beams are designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of tilt or differential settlement.
They consist of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised.
PENDULUM SYSTEM
In stock
HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.
