Geomotion are pleased to add the LT-Inclibus digital inclinometer to our ever expanding and comprehensive range of geotechnical instrumentation.
The standard LT-Inclibus system consists of segments of 2m long fibreglass rods with two biaxial waterproof MEMS inclinometer sensors spaced 1 metre apart. It can be installed both vertically and horizontally. Upon request it is possible to have up to 4 gauges on the 2m rod.
The rods are joined mechanically and the gauges connected in an RS485 chain, with a single cable running the length of the system connected to a data logger.
The chain of the LT-Inclibus digital inclinometer can be installed within a borehole, mounted to a surface of a structure, laid along a trench or buried in a concrete mass. It is used to monitor embankments, unstable slopes, settlements, LNG tanks, deep excavations, tunnelling, dam slope stability and bridge deck deformation.
- Real Time Monitoring
- Sensors are connected sequentially
- Easy and fast installation
- Modular and robust design
- Lightweight and flexible system
- The LT-Inclibus system is ideal for continuous, unattended monitoring and can deliver readings in real time
- Only one signal cable per borehole, quicker installation and simplified connection to the data logger
- Less post processing in the monitoring software resulting in the reduction of possible calculation errors
- Quicker and easier installation as segments can be installed in any order
The system contains a number of sensor nodes installed in either a vertical or horizontal configuration.
The joints between each sensor are robust, allowing the system to maintain a consistent orientation of all the nodes. The LT-Inclibus Digital Inclinometer system is typically installed so that it passes through a suspected zone of movement or area of interest.
The sensors can be spaced as close as 0.5 metres apart to provide a reading resolution the same as a standard traversing probe without the need for manual monitoring. Each gauge comes with biaxial sensors to detect movement in both a primary and secondary axis.
Inclination measurements from the nodes are processed to provide graphs of the system profile and changes to the profile over time. Changes indicate displacement (movement). The LT-Inclibus Digital Inclinometer system is connected to a data acquisition system, and readings can be automatically transmitted to processing software that can trigger alarms based on displacements or rate of change.
This inclinometer is commonly used to monitor:
- Unstable slopes
- LNG tanks
- Deep excavations
- Dam slope stability
- Bridge deck deformation
