Subsea Datalogging Tensile Link

The Subsea Datalogging Tensile Link is a robust Tensile Link used for measuring tensile loads on subsea mooring lines, underwater deployments and other similar applications. Available in load ranges from 5 tonne up to 200 tonne the instrument measures and records the applied load using an internal data logger which was developed by DLM Electronic Engineers.

Fully sealed to withstand subsea environments the load cell is capable of being deployed in up to 3000m water depth for periods of up to 1 year. Manufactured from stainless steel or nickel plated steel (depending on customers’ requirements) the load cell is pressure tested and fully calibrated after manufacture to ensure reliability and accuracy to the highest degree.

The internal data logger inside the tensile link is self-powered and enables load readings to be recorded at a maximum rate of 1Hz for periods of up to 12 months depending on the sample rate. data logs can be accessed by using the supplied subsea cable which is connected to the subsea connector mounted to the side of the load cell in a protective shroud. stored as .CSV file format the logs are easily accessible using already existing PC software like Microsoft Excel, enabling easy data processing after de mobbing.
