LVDT-based extensometer features a pressure-balanced, oil-filled and double bellows-sealed assembly to reliably monitor the stability of offshore drilling platforms, structural integrity of production risers, catenary risers, tendons, platform legs and braces. The LVDT measures the extension of structural members to a fraction of a microstrain.
Because measurement must be obtained in seawater depths down to 7,500 ft with external pressure of approximately 3,800 psi, the LVDT assembly is made from 316 Stainless Steel and Inconel 625 for pressure and corrosion resistance. The LVDT provides a useful signal back to the surface, even in great water depths, for monitoring, recording, and controlling thrusters and ballast transfer pumps.
