An inclinometer is an instrument that measures the angle of tilt (inclination) relative to the horizontal plane or to gravity. This makes small shifts and leaning movements measurable.
Use in geotechnics
In geotechnics and structural monitoring, an inclinometer is used to track movement in the ground or in structures:
- Probe in a casing: an inclinometer probe is lowered into a vertical measuring casing to measure horizontal ground displacement over depth.
- Around risk zones: this is done, for example, alongside excavations, sheet pile walls, dikes or retaining walls.
- Tilt sensors on buildings: sensors are placed on buildings to monitor leaning or settlement.
Why it matters
The measurements give early warning of whether the ground or a structure is moving. This makes it possible to intervene in time, helping to prevent damage to both the structure itself and its surroundings.
