DESCRIPTION

RST’s MEMS In-Place Tilt Meters measure tilt in either one or two axial planes perpendicular to the surface of the base plate. The unit is intended to be permanently installed to provide long term observation with maximum resolution and sensitivity, and is conveniently designed for manual monitoring or remote data acquisition.

MEMS systems consist of a tiltmeter mounting plate, interconnecting cable, and data logger or readout instrument. The tiltmeter may either be uniaxial or biaxial and is available in both horizontal and vertical versions. The electronics are housed in a NEMA 4X (IP-65) enclosure for environmental protection, and is typically bolted or bonded to the structure.

APPLICATIONS

  • Monitor tilt of retaining and building walls.
  • Tilt of concrete dams.
  • Structural load testing.
  • Landslide Monitoring
  • Building safety along adjacent excavations.
  • Applications where the failure mode is expected to have a rotational component.
  • Observation of benches and berms in open pit mines.
  • Bridge pier monitoring
  • Ground subsidence.
