Overview

RST’s In-Place Tiltmeters (MEMS) measure tilt in 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. The system consists of a tiltmeter mounting plate, interconnecting cable, and data logger or readout instrument. The electronics are housed in a NEMA 4X (IP-65) enclosure for environmental protection, and is typically bolted or bonded to the structure. For maximum resistance against water ingress, the cable is typically hard wired to the enclosure. The interconnecting cable is suitable for direct burial.

In-Place Tiltmeters are commonly used for:

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

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
