Subsea

The NORSUB MRU SUBSEA is ideal for any application that requires accurate and robust subsea motion measurements. The Subsea MRU is a very small and compact motion sensor that is depth rated to 6000 m. The small size and footprint make it easy to install almost anywhere. Communication options include ethernet, RS-232 and RS-485/422. A Subconn connector is used for both power and communication.

A high-end magnetometer can be included in the MRU to provide accurate magnetic heading.

The Subsea MRU comes in three different versions: 3000, 6000 and 9000 models to accommodate for different accuracy requirements and budgets.
