Tiltmeters mounted on stakes or poles can be used to trigger alerts when ground movements exceed alarm thresholds.
Tiltmeters mounted on structures are used to monitor stability. Mounting brackets are available for nearly every environment.
Tiltmeters mounted on arrays of vertical or horizontal beams can monitor differential settlement and deformation.
- Landslides & Rockfalls
- Embankment Failure
- Stability of piles & shoring
- Stability of structures potentially affected by excavations or tunneling
- Stability of piers during bridge renovations
- Stability of building facades during interior renovations
- Effects of pressure grouting
- Differential settlement and heave
Types of Tiltmeters
Wired Tiltmeters are electrolevel-based devices that are connected to a datalogger. The logger supplies powers and obtains readings. Electrolevel tiltmeters can be supplied with RS-485 interfaces when used in arrays.
Wireless Tiltmeters are MEMS-based, self-powered digital devices that provide high-resolution measurements, wide measurement ranges, built-in logger capabilities, and wireless communications to an internet gateway.
Wireless tiltmeters are preferred for their simplicity of operation, ease of installation, and high performance.
Laser-Tilts are laser distance meters with embedded tiltmeters. While the main function of the instrument is monitoring displacements with the laser, the tiltmeter can be used to verify that the laser is mounted in a stable location.
Wireless tiltmeters monitor stabililty of MSE wall during major repair work.
Airport jet bridge monitored by wireless tiltmeter during adjacent foundation work.
Wireless tiltmeters monitor stability of 40-foot high retaining wall above public parking lot.
