Description
The Subsea Data logging Tensile Link is a robust Tensile Link used for measuring loads on subsea mooring lines, underwater deployments and other similar applications. The instrument measures and records the applied load using an internal data logger which was developed by DLM Design Engineers.
The internal data logger inside the tensile link is self-powered and enables load readings to be recorded at a maximum rate of 800Hz for periods of up to 15 years 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 demobbing.
Key features
- Self-powered internal data logger
- Capable of recording up to 2 million load readings
- PC interface to download data in .CSV format
