TE Connectivity (TE) announced a new Macro Sensors SSIR 937 submersible LVDT position transmitters with a CANopen interface compliant with CiA 443 for subsea instruments. The transmitter offers more interoperable and standardized communications to network with devices from different manufacturers used on the ocean floor.

The new reliable LVDT position transmitter withstands deep sea environments with external pressures up to 7500 psi in excess of 1 million hours mean time between failure, when encased in special alloys. The sensor also offers extraordinary repeatability (error less than 0.01 percent of full range), regardless of offsets due to pressure and/or temperature.

TE’s Macro Sensors submersible LVDTs are used in a variety of subsea measurement systems, including 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 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.
