Bestech Australia presents a range of custom position sensing solutions for subsea and marine applications.

The Macro Sensors submersible LVDT position transmitters supplied by Bestech Australia incorporate major performance features for subsea and marine applications. High-pressure, spring-loaded for use in a 5,000 psi pressure-balanced, oil-filled container, the Marco Sensor LVDTs feature 316SS and Inconel 625 construction for pressure and corrosion resistance, with the LVDT assembly ensuring reliable operation and a long lifetime exceeding 10 years even when fully exposed to seawater.

The zero leakage pressure sealing in the LVDT is verified by helium mass spectrometer leak testing.

The seawater corrosion resistant LVDT position transmitters offer extraordinary repeatability, compatible 4-20ma loop-powered electronics, and signal feedback to the surface from deep water for monitoring, recording and controlling thrusters and ballast transfer pumps, while also ensuring the control of ‘Christmas Tree’ valves.

Constant monitoring of the structural integrity of production risers, catenary risers, tendons and platform legs and braces is necessary to ensure the ongoing stability of offshore drilling platforms. LVDT-based linear position sensors and gauging probes from Bestech Australia enhance the reliability by longitudinally mounting multiple redundant LVDT-based extensometers around the circumference of the structural member to monitor structural integrity. The extensometer housing can be outfitted with a variety of mechanical terminations to facilitate connection to the structural members.

Where total movement being measured for the huge loads on oil platforms is typically less than 2mm, Macro Sensors LVDTs enable measurement of the extension of the structural members to a fraction of a microstrain. 

Subsea level measurement can be accomplished with the use of a pressure sensor that requires certain mechanical considerations in order to survive the environment. A remotely operated vehicle (ROV) is lowered into the ocean with the pressure port either installed inside an enclosure or completely exposed to the seawater. As the ROV is submerged, the water pressure is exerted on the diaphragm of the pressure sensor, with the pressure rising with increasing depth.
