Description

The RST Submersible Tiltmeter provides precision real-time remote monitoring of tilt of submerged structures. It consists of a MEMS inclinometer sensor and electronics mounted inside a rugged waterproof enclosure. The instrument housing is machined from solid stainless steel, providing extreme endurance for long-term high-pressure underwater service. The cable entry is a submarine grade connector, which provides watertight performance at depths exceeding 200 meters.

Applications

  • Remote, real-time monitoring of inclination of concrete-face rockfill dam slabs and concrete dams.
  • Monitor tilt of retaining walls, piles, and bridge piers.
  • Monitoring of offshore structures.
  • Installation of submerged pipelines.
