About the SSB Series Submersible LVDT position transmitters

The SSB/SSBR series LVDTs are submersible position transmitters with a CANopen interface compliant to CiA 443 for subsea instruments. The CiA 443 CANopen profile offers more interoperable and standardized communications to network devices among different manufacturers used on the ocean floor.

The SSBR 937 Series Submersible LVDT Position Transmitters withstand deep sea environments with external pressures up to 7500 psi. These rugged, .94 inch [nom.] (24 mm) diameter sensors are available in standard ranges of 2.00 inches (50 mm), 3.00 inches (75 mm), 4.00 inches (100 mm), or 8.00 inches (200 mm) although other ranges are available at special request.

Reliability is of critical importance due to the cost of replacing subsea hardware. The sensors also offer extraordinary repeatability (error less than 0.01% of full range), regardless of offsets due to pressure.

Typical applications include elongation measurement as part of long-term finite element analysis of pipelines, derricks, moorings, choke valves and other critical high-stress members on offshore oil platforms that must be constantly monitored to ensure ongoing drilling platform stability. The submersible Position Sensors can measure the extension of structural members of oil platforms to a fraction of a microstrain. To ensure oil platforms don’t shift, movement is measured to less than 2mm.

Other features SSB-Series

  • High pressure Seacon-Brantner subsea connector standard
  • Available in either inline axial or radial connector configurations

Applications for SSB-Series

  • Off-shore drilling platforms
  • Pipeline monitoring
  • Choke valves
  • ROV and exploration
  • Mooring cables
  • Extensometers
